I have had several requests from members to start a sticky post so folks can quickly access reloading data for the various DTI calibers that Mike Milli/AKA DTech of Dedicated Technology custom builds.
Please Read:
Note that while this data was hopefully safe in the gun that it was developed it may not be in your particular gun so follow the usual protocol of starting low and work from there.

I think the following information would be helpful:

Caliber
Bullet type
Case brand
Primer brand/type
Powder/Charge weight
OAL
Barrel rate of twist
Velocity
Notes of accuracy/group sizes

Thanks,
David Stroud

KnockEm, stats on that deer and distance of shot? That's a fine deer for NY. My family has hunted Western NY all my/their life and only ever shot a couple that even could be talked about in the same conversation as that one.


The results for the 90gr Gamekings are promising, anyone tried a flat based bullet in that weight range? Only one that comes to mind is the 87gr Speer Hot-Cor. Curious if anyones gotten them over 3000 fps.

25 DTI - my deer load

25 DTI
100 grain sierra gameking
SSA Case
Remington 7 1/2 primerWinchester Small Rifle
32.0 grains of Hodgdon Leverevolution powder
2.26 inches oal
18 inch 1/10 twist. Shilen match
2800 fps
Sub MOA.

NOTES: You can use the Sierra 100 grain prohunter with the same OAL. Velocity will be slighly less due to more bearing surface of the bullet.

My bullet of choice is the Swift 100 grain A-Frame. Seated to 2.3 inches the velocity was about 2750 fps. Very accurate.

All other 100 grain bullets need to be seated deep in the case and the powder charges adjusted accordingly. The seating depths of the bullets I mentioned above are all about the same.

CAUTION: The port pressure on a mid-length barrel setup will be higher than most other powders (using the leverevolution). I used a Tubbs buffer system to slow up the unlocking time and eliminated any swipes that I had. I am considering installing a MGI adjustable gas tube. Also, my buffer weighs 5.0 oz (carbine)

With all of the test-firing I do around the shop, I pick up blems and close-outs whenever I can. Back a few years ago, Midway had a deal on .257 Cal. 90 Grain hollow-point flat-base bullets. They were made for Federal to use in their "Federal Premium" ammunition. I picked up 500 of them or so to use for testing the .25 WSSM's, but when I came out with the .25 DTI, they became pure magic! They are not only VERY accurate, but they are short enough to get me 3000 FPS out of an 18" barrel! As you load for rifles where magazine length is your COL deciding factor, you will quickly see what short bullets will do for you.

The first deer killed in the world with a .25 DTI was taken with that bullet. If you ever see them available, pick up as many of them as you can!

Thanks for the reply Mike. I recall you mentioning this. I was wondering if anyone had similar luck with a more readily available bullet. Seems like it would be very doable.

While I was working with different bullets for the .25 DTI, I noticed something interesting. If you compare the Sierra 100 grain spitzer to the 90 grain HP flat-base, they are identical but for 10 grains and the little lead point. It's surprising how much that little added length costs you...

Mike -- although I found that the bullet seating depth (amount of bullet in the case) is nearly the same for both bullets. The 90 grain gameking is 2.19 OAL and the 100 grain gameking is 2.26. That .07 inches as you say is the lead tip. I sure would like to be able to seat those 90 grain pills to 2.30 inches.

Disappointed by my most recent chrono session. I tried CCI#41 primers, 31.5 grains of H322, and a 70 grain BK. Velocity was only 3060 but vel was very uniform!! Looking at the case head, saw some smears so probably cannot go any higher.
100 grain Hornady spitzer, 32 grains LR, and CCI#41 primer, got me average of 2707 with some smears. The primers are difficult to seat so they flatten some before firing, they still appear to be right at the stopping point.
Was going to try some more but rain appeared.
My velocities at an earlier session was higher for some reason but with 7 1/2 primers. Will revisit this again

I got higher velocities with the 7 1/2's also. Something to note ---- I got my highest velocity with Sierra 100 gr. boatails. They were faster than the prohunters, hornady and swifts. Something to do with the bullet contact surface in the bore I suspect.

Also, I run a heavy buffer system by tubbs. That got rid of my swipes.

I will give this a try but I am not technically inclined so I may just confuse you more.
A swipe occurs when the bolt tries to turn and unlock before the pressure has dropped sufficiently for the case to release its grip on the chamber.
This can be a high pressure issue or a timing issue. Timing issues seem to occur more often in carbine or sometimes midlength rifles.
Timing issues occur when the peak pressure is not excessive but the pressure arriving at the bolt occurs too early in the progressive ignition sequence.
Anyway feel free to correct me if I am wrong!

I am returning to Rem 7 1/2s. I found no advantage to the higher priced #41's and like you lost velocity.
I have a bunch of BN coated bullets to shoot but they are with the #41s. I will shoot them just for a bit more history of how they work versus the Remmys.

someone on here posted the max fps he obtained as 2900. But....he did not list the powder or charge weight. Screen name may be Siringo if that is any help. He also may have some info on heavier bullets as I think that is his thing, which may not be a bad thing to consider!
Hope this helps!

6mmDTI 22 inch barrel 1 in 10 . So far I have tried H4895 Fed primers 205M with OAL of 2.260 With very good results. This is the load that I took a deer with this year. I tried .010 , .020 and .030 off the lands and .020 is the best. This load is also showing signs of pressure. First time with Varget 29gr is the best and 29.2 showed some flatting of the primer.

Yep --- heavies are my thing. I could not get the 80's to shoot fast enough so I abandoned the whole idea. I also thought that these bullets were designed for larger faster cartridges, so it may not perform well ---- at least that was my uneducated thought. The bullet also is quite long and eats up as much powder space as a 100 grain.

Good to see you back Siringo. I have tried the LRV powder on 90 grain Sierra HPBTs and got 2900 with 33 grains. The 100 grain Hornady gave me 2702 with 32 grains and no pressure. With my gun it is slow with the normally listed powders but as you stated LRV is good for the heavier stuff!
THanks for the info and what bullet did you end up settling on! I called Barnes and they think the 80 grain TTSX at 2900 should be fine out to 200 yards.

I've been working with one of Mike's 30 WSSM over the past summer, so I did not do much with the 25 DTI this year. One thing with the 100 bullet speed, when using the Sierra 100 boatail, I got 50 fps more speed than with the Swift 100's. Could this be because of the bearing surface??

I have a few prohunters left and will compare them side by side with the boatails on speed.

GregH - were you using Remington 7 1/2's or CCI 41's?

I also loaded up a bunch of 90's with varying charges and I sure would like to push those to 3000.

i have tried both 41's and 7 1/2's. I am going to reshoot some stuff with the 7 1/2's but I think it may be an overall better primer. I showered lower speeds and more pressure with 41's on my last chrono session. I will just have to wait to shoot again before making a final decision. I will post the results.
How is the 30 WSSM working out?
Thanks in advance

Braved the cold --- put on the wool clothes, mukluks and headed to the range. It was 8 degrees this morning. I wanted to see what my velocities were in this extreme cold with different primers (with my pet deer load).

My base deer load is 32.0 grains of LeverEvolution powder. Note on a previous post that I said I was using Remington 7 1/2 primers. This was not correct and I edited my post. I was using Winchester small rifle primers.

Rifle is 25 DTI, 18 inch. Bullets were Sierra 100 grain BT loaded to 2.26 inches. During my load testing this was sub moa and velocity was 2830 FPS. The temperature at that time was 70 degrees to 80 degrees for the load development.

In contrast -- today is nearly 70 degrees colder than when I developed that load. I do use Quick Load and there is no reference to LeverEvolution in the most recent version. So I fudge with WW748. From 80 degrees to 8 degrees, WW748 loses 100+ fps. SOO --- I kinda figured I would lose something similar with the LeverEvolution.

Using the same bullet (Sierra 100 BT), Powder Charge (32.0 of LeverEvolution) and OAL (2.26), I fired the following:

Remington 7 1/2
1. 2656 fps
2. 2715 fps
3. 2688 fps
4. 2743 fps
5. 2650 fps
AV - 2690 fps
ES - 93 fps
SD - 39 fps
Group - 1" W x 1.25" H

Wolf Small Rifle Magnum
1. 2721 fps
2. 2760 fps
3. 2704 fps
4. 2732 fps
5. 2682 fps
AV - 2719 fps
ES - 78 fps
SD - 29 fps
Group - 1" W x 1.25" H

Winchester Small Rifle (4 shots only, ran out of bullets)
1. 2726 fps
2. 2732 fps
3. 2749 fps
4. 2732 fps
AV - 2734 fps
ES - 23 fps
SD - 9 fps
Group - 3/4" W x 3/4" H

As a side note --- I also shot some Remington Corelok 100 grain bullets. Velocities were about the same --- maybe a little higher, but I seated them to 2.23 inches (at the cannelure) so the pressures were most likely higher. However, group size was twice the size in comparison to the Sierras.

Siringo, THanks for the load update. I copied your load of 32 grains of LVR, Rem 7 1/2 primer and a 100 grain Interlock and the average was 2706, don't have the other figures with me, temp would have been about 60 degrees.
I was feeling adventurous,and tried 33 grains of LVR and the 90 grain Sierra BTHP, average 2906 with it! Thankfully it never gets below about 20 degrees on a normal year here. Sounds like with the 18 inch barrel we are stuck about 2700 in hunting weather.
My fastest load with the 75 VMax has been 33.7 grains of TAC for 3060 fps. I tried 322 and Exterminator and such, I suppose each gun is an individual!
Thanks again
Greg Harrison

Greg --- pick up some Sierra 100 grain game kings (BT). Use the Winchester small rifle primer. With the 100 grain Remington my average was 2743 -- Using the Winchester primer.

I also shot some 90 grain game kings that day.

33.3 - grs of LV -- 2888 fps
33.6 grs of LV -- 2924 (best group under 1 inch)
34.o grs of LV -- 2931

Used the WSR primer and again it was 8 degrees out.

You are correct that at hunting temps, the best we could see would be in the mid 2700's. Still nothing to sneeze at though.

I shot 2 deer this year and performance with the 90 HPBT was okay. At about 2850 neither exited but both at 40 yards into dense muscle on one shot, it was devastating. ON the other , about 125 yard thru the ribs, it broke ribs on both sides and completely severed the top of the heart so yeah the 25 is till prettty robust. Good luck and and thanks for the tips!!

I have shot 4 whitetail does with my 25 DTi predator load just recently and none have gone more than 20 yards and two dropped in their tracks. The load is 28.7gr of N133 with the 85gr Nosler BT. Speed is right at 2900fps and it is a good load for knocking down coyotes but I have gotten almost all pass-thru's on broadside hits. Bobcats have had quarter sized exits and fox... not too pretty.

I figured the 85 BT would be a tad too long but that is what I get for thinking. Glad it worked. I will probably stick with the 75 vmax and 70 BK's since that is what I have a stock of. I tried the Boron Nitride plating but could see no advantage s of yet! hanks for the new load
Good shooting

This post is related to reloading the 25 DTI, but more to do with powder/gas system when using Lever Evolution Powder.

I recently installed a MGI Mid length regulated gas tube on the 25DTI. I have a medium heavy barrel with a .875 diameter gas block. The past weekend it was quite cold in northern MN (-16 degrees below), and I ended up setting the set screw for the gas regulator at 1 3/4 turns. At this setting it feed, shucked, reloaded and held back on on empty magazine. Cases piled up nicely 3 feet from me. Also, there was no evidence of any swipes on the cases or pressure signs. The load I used was the same as I have posted before with the 100 grain Sierra BT. Lever Evolution is like Superformance in that it has a longer peak pressure duration. Something that mid length and carbine length gas systems do not like. A rifle length system would most likely not have the issues (unlocking too soon).

BTW --- the installation instructions say to open the value 2 1/2 turns and then open more as needed to lock open on an empty magazine. I had to go the other way. ALSO, this really only applies to the use of Lever Evolution Powder, not the other types such as H4895, Tac, ect.

Thanks Siringo! I have some more of the 32 grains of LR loaded up but havent got to shoot it and give it it a good check for swipes.. THe last time I tried that load with 100 grain Hornady SP bullets and #41 primers it shot ave of 2700 with no swipes that I remember and no flat primers. My barrel is .750 at the gas block, just an observation. I think temp was about 50 degrees, when I reshoot with the 7 1/2 primers I will check for swipes again to be sure! Thanks for the good info on the LR and heavy bullets!

Fun to work with this. BTW ---- I tried the Hornady's and they did not shoot as well as the Sierra's.

My next adventure is I have a box of 117 grain Round Nose! I have to wait for it to get warmer though.

25 DTI and 117 Grain Hornady Round Nose

I had some of these bullets that I planned on playing with when the weather got warmer. Seems that is never going to happen here in Minnesota this year. May 2nd and it is snowing today!

Anyway, my 25 DTI as I have posted before has a MGI adjustable gas tube on an 18 inch barrel. All of the loads listed below are with LeverEvolution and I SERIOUSLY CAUTION using anything listed below without an adjustable tube or block ---- because the port pressures are significantly higher than other powders.

In general, the 25 DTI does not have enough case capacity to do much with these bullets and I would consider them only "woods" bullets for ranges less than 100 yards. Although, the velocity of these loads are a couple hundred feet per second faster than a 25-35 out of a 24 inch barrel.

USING LEVEREVOLUTION AND WINCHESTER SMALL RIFLE PRIMERS. OAL = 2.20 INCHES.

(Outside Temperature during test = 10 degrees)
28.0 Grains - 2310 fps -- 3 shot group = 1 1/2 inch
28.5 grains - 2325 fps -- 3 shot group = 1 1/4 inch
29.0 grains - 2416 fps -- 3 shot group = 1 inch
29.5 grains - 2440 fps -- 3 shot group = 3/4 inch
30.0 grains - 2493 fps -- 3 shot group = 1/2 inch
(outside temperature 45 degrees and extremely windy. Not good for shooting groups)
30.0 grains - 2553 fps -- primer flattening
30.2 grains - 2567 fps -- primer flattening/slight crater
30.4 grains - 2580 fps -- primer flattening/cratering
30.6 grains - 2592 fps -- primer flattening/major crater

30.8 grains - 2616 fps -- primer flattened/heavy crater/swipes ---HOT< HOT< HOT

The groups sizes above varied between 1 1/2 inches and 1 inch. Since this bullet would only be used for deer at ranges less than 100 yards --- that is totally acceptable.

NOTICE THE VELOCITY INCREASE FROM 10 DEGREES TO 45 DEGREES. ALSO THE FIRST LOADS MAY HAVE BEEN USING REMINGTON 7 1/2 PRIMERS. THE WINCHESTERS GIVE ME HIGHER VELOCITY.

My pick would be something between 29.5 grains and 30.0 grains. CAUTION ---- USE THIS DATA AT YOUR OWN RISK.

A little more shooting today to confirm some results --- plUS it was really nice weather --- finally.

25 DTI, Winchester Small Rifle, Adjustable Gas Tube.
_______________________________________________________________
100 grain Sierra Gameking Boatail --- 2.25 OAL

32.0 grains of LeverEvolution (OK)
Average Velocity -- 2817 fps
ES -- 17 fps
SD -- 7 fps

32.2 grains of LeverEvolution (Warm)
Average Velocity -- 2840 fps
ES -- 31 fps
SD -- 12 fps

32.4 grains of LeverEvolution (Hot)
Average -- 2854
ES -- 44 fps
SD -- 18
-------------------------------------------------------
90 grain Sierra Gameking Hollow Point

33.6 grains of LeverEvolution -- 2.19 inches OAL
Average Velocity -- 2986 fps
ES--34 fps
SD --13 fps
------------------------------------------------------------
117 grain Hornady Round Nose

29.8 grains of LeverEvolution -- 2.20 inches OAL
Average Velocity -- 2513 fps
ES -- 34 fps
SD -- 13 fps

ACCURACY WISE THE 32 GRAIN LOAD IS MOA OR A LITTLE LESS. ALL THE OTHERS ARE SLIGHTLY OVER, BUT THESE ARE FOR SHOOTING DEER, NOT FLIES.

Now on to some varmint bullets with clean powder.

Thanks as always for the new load date. You are a little more adventuresome(braver) than I am. With the 90 grainer I tried 33.0 LVR for 2900.
Thanks again!

I must have a slow 25DTI ! The best I can do with 75 Vmaxs is 3060 with 33.7 grains of TAC. 31.2 grains of H322 gets me about the same velocity.
32 grains of LVR only gets me 2720 with the Sierra SBT 100 grainer. 33 grains of LVR and the 90 HPBT Sierra goes around 2900. 100 grain Nosler Partition and 100 grain Interlock shoed about the same velocity as the Sierra SBT. Could not locate Win SR primers at this time.
I will list some others when I find my notebook. These are BN coated bullets. All are shot with 7 1/2 primers, 18 inch barrel, temp was about 85 degrees.
No serious swipes noted and primers still showed rounded edges with no cratering.
Goes to prove all rifles are individuals!

Thanks for the load data guys!

Without reading back to see what all speeds everyone is getting that actually that sounds about right to me. My main load of 85gr Noslerís is running 2900fps so dropping 10gr bullet weight and getting 160 fps gain sounds reasonable.
Think about it this way in the 250 Savage they dropped the bullet weight to 87gr to get 3000fps and thatís burning more powder from a longer barrel. I realize they were keeping pressures a little low but hey they still do on factory ammo. cool Pretty efficient little round.

Venatic,
I really did not mean to be complaining. You are right , it is a really efficient. I had read where some others had 2800 on the 100 grainers and mine just won't do it. But 2700 is plenty and the deer won't even notice it. I might have asked before but why did you decide to use the 85 grain BT? just curious! And thanks for all the data you have provided!

Siringo, I have not found any yet. But I am going to try them as soon as I can . Thanks for the info, I had been on the look out for some. There was a rumor that the new Win SR primers were too soft for use in AR's. I have no idea where that started or where it ends. But I will try some@@

HUMMMM ---- wonder what Winchester uses in their own 5.56 ammo?

Anyway --- I have found in the 450 Bushmaster and 25 DTI that WSR give me the highest velocities and good accuracy. Rem 7 1/2 give slightly better accuracy for me, but little slower.

I too wonder what Winchesters uses. We know they use their regular SR primer but rumors have a way of creating questions for no reason. THanks for the reality check!!!

I just finished checking some COAL's in my 25 DTI. I was curious as to how closely Mike is able to duplicate these rifles. Here are some examples. Length shown is measured to the throat contact point.

90 grain Sierra HPBT-2.215
75 Grain Vmax-2.32
70 Grain Blitz King-2.305
100 Grain Sierra Spitzer BT-2.27
100 Grain Speer HotCor-2.285
100 Grain Hornady Spitzer-2.292
87 grain Hornady Spitzer-2.30
100 Grain Nosler Partition-2.36
75 Grain Hornady HP-2.192

If any of you guys see an error here please let me know.
Happy Shootin'

25 DTI 18 inch barrel Heavy Match Contour
Results from chrono sessions did not result in any new revelations! I think Venatic, Siringo and others have covered most of the bases.
Here is what I have gotten.
10-18-12 80 degrees, sunny, but weapon not in direct sunlight

Powder-8208 Primer-Rem7 1/2
Bullet-70 Sie BK

31.5 Grains
Av Vel-2921 ES-71.40 SD 36.6

32.0 Grains
AV Vel-3030 ES-55.42 SD-28.01
Primer still round, no swipes.
Velocity okay speedwise but consistency could be better.
Accuracy at 100 yards was about 1 inch.
On this session, I got the 2 in one hole and 1 about 3/4 inch away syndrome.

I tried CFE with 75 grain Vmaxes. loads were form 33 to 34 grains. Velocity topped out at 2812 , with no pressure but velocity too low to interest me.


LeverRevolution 32.5 Grains 100 Grain Sie BT Primer Rem 7 1/2
Av Vel-2781 ES-15.98 SD 11.31
Primer still rounded, and swipes evident. No gain over 32.0 grains.

CFE 32.5 grains with th Sie 100 grain BT
Av Vel- 2718 ES-32.37 SD-16.64
Primer appeared still rounded, but swipes were visible. No gain over 32.0 grains.

Accuracy with both 100 grain loads were excellent. Sub 1 inch.


Powder-BLC2 Primer Rem 7 1/2 Bullet- 100 Horn Spitzer
32 grains
AV Vel-2632 ES-38.61 SD-21.18
Primers looked good and no swipes.


My goto's are:

LeverRevolution 33.0 grains Rem Primer 90 grain SHPBT
Av Vel- 2900 Accuracy good- deer killing excellent

LeverRevolution 32.0 Grains 100 Grain Nosler Partition or Sie BT Spitzer
AV Vel-2682 ES-11.29 SD 6.40
Have not killed a deer with this one, but it has promise in my mind. I will test it this year.

I keep coming up with this one in my notes where I have marked it with a star due to accuracy and speed. I have shot it over the last year on several occasions with consistent results.

TAC Powder Rem Primer 70 grain BK or 75 Grain VMax
33.7 Grains AV Vel-3061 ES-43.39 SD-22.11
Primers looked ok and no or minimum swipes! It is a coyote killer!!

All cases used were SSA.
I know this isn't ground breaking but hope it helps someone somewhere. I know I have enjoyed working with the DTI. I have other data with 322, Ext, and Benchmark but it was all hohum!
Good Shootin' Guys

Greg

Great information Greg!!!! Regarding the swipes ---- as an experiment I installed a regulated gas tube from MGI. With the Leverevolution powder, I eliminated the swipes and can set the action to function in sub zero weather or 80 degree days.

There is not a good selection of adjustable gas blocks for the .875 diameter barrel. I sure wish someone would make an adjustable block similar to Ruger's adjustable piston system --- rather that use allen set screws. YOU HEAR THAT MIKE!!!!!!!!!

Siringo,
My loads are basically what you already came up with. The LR stuff was really good. I will have to try the 80 grain TTSX. It's not that I don't believe your info at all, I just like to play around. 8208 may be the ticket for it. No magic powder , I know, but I can hope.
My barrel is a different countour. Mine is .750 at the gas block then .730 to the muzzle. I asked Mike about last week and he advised he did'nt know if he had room to make them adjustable. But we can help. I have a CS extra strenth buffer spring from,I think JP Enterprises. That may help a little. I may go the adj. block route just cause I can, but I like the 25 DTI written on my gas block, not really a good reason not to change it, I know.
Deer season here opened yesterday but I work weekends and can't try any of the new loads on deer yet!

While working on another upper/caliber, I purchased an adjustable gas block from Wilson combat (.750) carbine length. Unfortunately, it would not fit under Mike's Handguard (their on-line lit was not clear). But I liked it because I could adjust if from the front. I'll save it for another day.

Regarding the 80 grain --- my tests were very limited. It is such a long bullet. BUT if you can get it going 3000 fps ---- GREAT.

Also -- for those that read this forum, the November issue of Shooting Times has a good article on the 250 Savage. Writer used a 22 inch barrel Savage and for the most part was getting the same velocities as the 25 DTI produces. COOL!

I read the article, it was pretty good. I wish I could duplicate his load with the 80 Grain TTSX. That would be pretty devastating. I am gonna purchase an adjustable bas block, just don't know which one yet. Still looking !

Just got thru doing a little shooting with 8208 and 75 Grain Vmax loaded to 2.29. I found a pressure peak really quick due to poor load testing practices.
I tried 31 grains with ok results, no pressure signs and speed averaging 2880. I got brave and jumped to 31.5 grains and was rewarded with 2921. I got really brave and loaded 32.0. On this load I got an average of 3031. To me that is a heck of a jump and would indicate a spike to say the least!
Even [beeep] I got the 100 fps jump, I loaded up 2 more loads, 32.2. and 32.4. I will try that and see where it goes. Still have not gotten to really try out the new Adj. Gas Block I installed!

I use Hornady's Website.

Go to www.hornady.com

On the site is a ballistic program that you can use. Also, in their bullet list, you will find the ballistic coefficients for their bullets.

For those of you with 25DTI' do you fire form all your brass with low charges first? I was doing a ladder for my new upper and started to see some pressure signs and possibly coining of the brass (could be the bolt). Anyway after I got home and started looking at the primers I started to think that the pressures could have been higher because the neck was being pushed out. Any input?

I haven't, but I ruined brass in the beginning by loading too hot. Once I got the load down, it didn't matter much.

What is "coning"?

What brand of brass are you using?

Sorry, I meant coining, like having the ejector or some part of the bolt punch a shape in the back of the brass. I saw it on even the loads I made on the low end of the ladder. I loaded up a ladder of 90gr SGK's using H335 and TAC and it happened on both powders which made me wonder if it was because the brass wasn't fire formed yet.

Sierra GK's
COAL 2.19
TAC 28.5gr- 31g
H335 27.9-30.4g
Loaded in new SSA brass

According to Mike M. Fire formed cases will hold about 1 grain more powder. Might be prudent to cut back 1.0 to 1.5 gars to fire form from your max.

I have a quick load program and the case capacity default says 36.9 grains of H2O. My SSA cases averaged 35.7 grs and hornady was 34.0.

Using 35.7 as a base line for SSA cases, using 30.5 grains of TAC would yield 55 psi and 30.0 grains of H335 would be about the same. 55k psi is the default max (actually 54,998). Your max load with my case capacity pushes the pressure to 57k+.

If I used your max TAC load in a hornady case - pressure would be 65k. I measure the unformed cases at one time but have misplaced it. If I recall the unformed SSA case was very close to the formed hornady case.

I AM NOT AN EXPERT BY ANY MEANS ON QUICK LOAD.

The 80gr TTSX at 2.295" works great in my 18" BHW 25x6.8, which is essentially the same cartridge. 3000fps is doable with a few different powders and doesn't trash the brass.

This link is my load data for the 25x6.8 and should be close enough to use as a reference for the 25DTI. Same warnings as always, start low, work up, different rifles/barrels/etc perform different, don't be stupid.

Wow! Great information. I have been curious about AA2200.

I should have check this out first before I commented, but I have no prior knowledge of the 25 x 6.8 by Black Hole. IF that cartridge is simply a necked down version of the 6.8, then the case capacity will be the same as an unfireformed 25 DTI -- which is 35 grains of H20. The vast majority of these loads are WAY overpressure.

It is a simple neck down. I haven't been getting any pressure signs other than some light primer crater and slight flattening. Like it says in the spreadsheet, some of the loads might be max and work your way up. They functioned safely in my rifle but not all of those are loads I will shoot everyday.

Not my picture, but the third from the left is the worst I've seen with my reloads and not commonly seen. The BHW poly rifling is known to reduce pressures across the board. I have reloaded hot loads up to 5x in the sane brass with no issues.

I've been working with my 25DTI using the Barnes 80 grain TTSX over H322 with a Remington 7 1/2 SRBR primer and have a one ragged hole @ 100 yards. Primers lightly flattened and no over pressure signs. I hope to chrono them within the next couple weeks.

Ended up with 3120 fps average.

What charge weight for the H322? It gives me good accuracy but not the speed of other powders.

30.5 grains H322. I have a 22" barrel and have been getting 2900-3100 fps during development. Some powders gave me the speed I needed, but not the accuracy.

Does anyone have information for the 6MM DTI shooting 65 grain V-Max? I've heard Benchmark is good with these but I have not seen anything about this particular bullet.

I've been thinking about trying it for heavier bullets. It is a reformulated RL15 and supposed to burn faster, more like Varget. I tried RL15 and it was way too slow.

What is a DTi? Rifle and or Cartridge? Sounds interesting don't know anything about them. So an education would be nice. The only stupid question is the one not asked?

A series of wildcat cartridges based on a necked down 6.8SPC case, by a company called DTI.

Anyone try GS custom bullets? Their 80gr is similar in length to the gameking at .95". I might buy a box or two and give them a whirl, but figured I'd see if anyone here has anything to say about them.

Got my GS Custom bullets on Friday and loaded a small batch. Hope to get them out and shoot them soon with the chrono. Apparently the 67gr is the correct bullet for the cartridge since I was hoping for heavier for hunting, but hopefully the solid bullet and extra speed make up for it.

Rem 7/1/2 primer

What are you expecting for speeds? I looked at GS's website and don't find this bullet. 85 is the lightest.

Just loaded the first rung but after giving him all the pertinent data he sent back a speed of 3300 with IMR 4227 but we will see once it passed over the magneto speed. His part number is 257067HV. Kind of odd but he suggests starting at max because of the drive bands. I started emailing him thinking the 85 was the ticket (maybe a bit more speed than the gameking) and a better hunting bullet but he said it was too long of a protrusion.

Bobtails -

Have you been able to get any data on the 65 gr. V-Maxes that you were looking for? If so, would you share it? I'm not intuitive enough to look at a load with another bullet weight than what I want to shoot and come up with what I need.

Any help would be appreciated.

Shot my first two trials (odd finding speed before accuracy). I got 3100fps out of 25gr of IMR 4227 and about 3128 out of 25.2. Odd thing is that I'm getting failure to eject/extract (didn't get to see if the bolt was cycling since I was shooting by myself). Odd because I never had any problems with any of the other load development.

IMR 4227 is a fast powder. My guess is your port pressure is low and not enough gas pressure to work the action (doesn't mean chamber pressure is low). Try shooting just one round with an empty magazine in the rifle. See if the bolt locks back. It very well may be that the combination of the light bullet for caliber and fast powder is not compatable with the gas system.

One bullet and the empty magazine would not lock the bolt back. I shot six shots, and only the first actually cycled the bolt. Is there a chart out there that has burn rates of powders? A one stop place rather than sifting through every manufacturer site.

Burn rate has nothing to do with it. Powders side by side on the chart will often exhibit different levels of reliability. You can load hotter for more gas, or drill the gas port for more gas flow. If you do the second you can often put an adjustable gas block on it and tune the gas to the load and broaden your operational envelope.

Even some factory ammo won't cycle AR's that run perfectly with other brands. If it is a new rifle often a couple hundred rounds will smooth things up and the issue goes away.

Greg

PS: Don't forget to try a different magazine as this will sometimes be an issue.

MadCow -- Back in 2014 you were shooting 90 grain Sierra's. Did those cycle? You were stating that you had higher pressure signs -- swipes. I have to assume that the cases were ejecting.

If the upper was functioning fine with other loads you have used, your problem will be the bullet/powder combination you are currently trying to use.

What barrel length are you using?

18" barrel, and yeah the 90gr always cycled fine. I'm seeing similar markings with the lighter bullet load as well, so it may not be the load as much as the chamber and bolt on this gun itself. Both loads leave a nice little circle on the headstamp and the feedramps leave two drag marks on the bullet and neck of the case. I'm not seeing any primer flattening, but I am getting a bit of cratering with the lighter bullet compared to the load I was using with the 90gr

I'm not surprised 4227 will not cycle your AR. Port pressure has to be awful low with that fast of a burning powder. Try 8208 or something in that range and your issues will go away.

The creator of the bullets says to start work with the max load (seemed goofy to me, so I just smaller ladders to look for pressure) but didn't see any extreme signs once I got to max with the 4227. Would getting a copy of quickload allow me to enter my case capacity, barrel length, etc. in to build a custom cartridge?

QL is nice as a what if tool. It does not always reflect real world numbers. I like to run it with known data to see if it is close. If so I will use the data as a general set of parameters but I don't blithely just jump on the numbers it generates. It is fascinating to plug in loads that some guys shoot. The eye opening pressures give me palpitations. It can be off but at times you know what they are running is very real and very scary.

We do use it early on in wildcat design but only as a part of the puzzle.

Looking for some quickload help for the 25DTI. I started with the 6.8 as the cartridge, and I was curious as to what people are putting in as the groove caliber, and the cross-sectional bore area. Just loaded the program and figured I'd start with a difficult cartridge rather than start out with something like 300win mag.

I just grabbed the numbers off the 25-06 and plugged them in on the 25X6.8. Of course you have to add your own case capacity.

30.5gr AR COMP
67gr GS Custom
SSA brass (35.9gr capacity)
2.27" OAL

200 yard range was the only thing that was open and since I was just checking for speed and functionality of the powder above and 8208 it was fine. Was pretty windy, so I'll really be looking forward to what this load can do when it is calm
This was the AR COMP, the top right was a 31.5 load to check for node speed.



Both 8208 and ARCOMP cycled fine, had no pressure signs FPS were as follows:

30.8gr of 8208XBR 3 shot average of 3053

30.5gr of ARCOMP 3 shot average of 3123

I'll be loading more up of the ARCOMP and heading back out soon

Thanks for all the input earlier.

man do I love this upper!

After being disappointed by my reloading skills yet again using the 67gr GSCustom bullets (106% case capacity or OAL is causing some problems I'm trying to figure out) I broke out my proven load when helping set up for a local 3-gun event. At 250 testing a swinger setup I put down a two round set that are touching. The guy who built the targets asked where I hit because you could see the target swing on the second shot and hear the hit, but no other paint blot was missing. get down there and you can see where the hollow point hit first.



You can see where I jerked the second shot at the 300 yard target

Shot some rounds through water jugs after I figured our my loading problems with the GS Customs (compressed load+ less surface area= bullet sliding forward) and got some pretty cool bullet pulls out of water bottles. While maybe not the best way to capture bullet deformation at least we stacked containers up in the same order. The local grocery store somehow got sold out of drinkingwater 1.5 gallon containers.

Anyway after having to seat the GS custom to 2.16 OAL, I'm thinking of calling the owner and asking what the extra length would get me in weight since I'd like something heavier than 67gr for deer. Either way I really liked the expansion and uniformity of it. Grouping was pretty good too.









I also weighed them. The game king weighed 33.9gr of the 90gr

original weight. Being that it started as a varmint round I'd

like to try it again and try to catch more bits of it. The GS

Custom weighed in at 66.9 of the original 67grains it started

at.

This post is in regards to 22 Nosler Cases.

I purchased a box of 22 Nosler ammo and pulled the bullets. As far as I could tell with prints and measurements, these cases could be used to make 25 DTI cases (with 223 case heads). I assembled some ammo in my SSA cases and Nosler cases using 32 grains of LeverEvolution, 100 grain Sierra BT and Winchester primers. I had done a rough check on the case capacity with the powder and they appeared close enough.

I shot them at 100 yards and the Nosler cases shot a nice 3/4 in group. The SSA Cases where slightly over an inch, but these cases have been used numerous times without annealing.

The Nosler cases showed slight wipes. Also checked the velocity and the the SSA cases averaged 2750 fps and the nosler cases averaged 2780 fps.

I resized both brands, cleaned in a sonic cleaner, cleaned the primer pockets and uniformed the lengths.

The control SSA group of 10 cases had a weight variation from 111.0 to 113.5 grains. The water capacity varied from 35.8 to 36.3 grains with an average of 36.0 grains.

The Nosler cases (20 of them) had a weight variation of 107.6 to 113.7 grains. The water capacity varied from 35.2 to 35.6 grains with an average of 35.4 grains. The variation of case weight could be attributed to turning the case head down to 223 dimensions.

Whole point of this exercise to see if the 22 nosler case COULD be used. I am not sure how strong the Nosler case head is, but the SSA case has a nice hard head.

Oh --- I just used a bolt carrier with a 223 bolt from another rifle. Worked like a champ.

Thanks for taking the time and effort to try out the 22 Nosler cases.
It is nice to know that we have options in chooseing cases and bolts for that matter.
thanks again
