Reloading data for 300 blackout.

the new 135 FTX that hornady just introduced has me intrigued though. i hope they release it as a component soon and not just loaded ammo.

i've had some impressive early results with the Sierra 135gr Varminter (#2124) when i got selected to participate in an ammo test for Ozark a while back. Those are going to see a little more attention from me this summer.

This one?

that'd be the one.
 
i was selected to participate in a test program for ozark ammo before they let them out in the wild. unfortunatly i was only given 10 round to play with.. however...

testing was done at 64 yds - i didnt feel like working my way all around the swamp to hang the 100 yd board.

.976 moa (.654") & .640 moa (.429") ctc respectively

temp was 30.5*F

Chrono info is as follows

CMMG 1:7 16" Carbine gassed barrel
Rem 120 OTM - 2101 FPS avg (5 shots), SD: 8.0
Ozark 135gr - 2155 FPS avg (3 shots), SD: 31.7
Ozark 147gr - 1606 FPS AVG (5 shots), SD: 9.1

AAC 9" 1:7 pistol gassed barrel
Rem 120 OTM - 1983 FPS Avg (5 shots), SD: 13.0
Ozark 135gr - 2015 fps (one shot only)
Ozark 147gr - 1473 FPS Avg (5 shots), SD: 14.6


i have not had a chance to do any kind of load developement yet, but i'm betting i could easily get them to be a half MOA load if factory loads shoot like this.

their 147gr M80 ammo is garbage. minute of softball.

Talked with a Hornady bullet designer at NRA-2016-KY, about the (30-30) 160 gr FTX expansion vs BO fps.
He said it should expand well at 1300 fps impact due to the large cavity of the ballistic tip and its thin jacket.
That's what I wanted to hear, so this pill should be good at typical ranges for me in Georgia.

Also asked about resizing the 100 gr 32 cal XTP to 0.308" for BO fps, he said it would be more prone to failure at the cannelure,
otherwise should expanded as designed (magnum pistol fps).

Picked up half dozen new Sierra 135 gr Varmint hollow point samples to experiment with,
they look promising for BO, with BC 0.308 @ 1900 FPS.

Yah, the 100 gr XTP (.312) sized to .308 is a little longer than the 90 gr but still has feed problems in an AR.
100 gr XTP
I was going to look for a different rib design on mags before giving up on that round.

your numbers seemed to conflict with what i recall in the past regarding these bullets .... i fired off an e-mail to tech@ hornady and got a response more to what i was recalling the normal expansion velocity of the 160 FTX (and the FTX bullet line in general) being

this is what they sent me

which also matches very closely to my inquiry about the 135 FTX that they just only released as ammo in 2016

i really do wish they would just publish the terminal velocity information on their website for all their bullets. that would save a LOT of time and trouble and make sure that their folks are giving out consistent information.



the only 150-160gr bullet i'm aware of right now thats for sale that expands at those kinda speeds is the outlawstate "subsonic" 155gr and the maker "rex" bullets (which i understand are still in the final stages of testing and are not available out in the wild quite yet)
http://www.makerbullets.com/proddetail.php?prod=308150BLK
http://www.outlawstatebullets.com/2.html

both of these bullets should perform easily down to 1300, and IIRC as a subsonic offering the makers should expand down to about 800 FPS or so.

the 200 REX subsonic they make expands down below 700 fps

He may have mis-spoke, but I repeated it to make sure I heard right, "1300 fps at impact for expansion".
I had the catalogue page opened to the 160 FTX and started the conversation by showing him that page.
Wish I had his name.
The 30-30 version has 1800 muzzle fps as lower limit, and that still gives me hope, 9th ed page 94.
 
trust me when i say i went into the e-mail hoping you were right. a $0.32 160gr poly tip bullet that expanded to 1300 FPS would be an awesome addition to the blackout hunters arsenal. that would be [beeep] near hold grail status for the caliber to the whitetail and piggy folks.


as i said, i sorely wish bullet manufacturers would just publish the terminal velocity required for expansion on their bullets along with the BC and such to eliminate the guesswork and miscommunications.
 
You're right. He mis-spoke.
Here's a page from the same manual I pointed out, at the show.
It shows 1700 fps for that bullet, not 1300 fps:

Interesting coincidence, was checking out a (new to me) small LGS yesterday,
and the owner had a box of FTX-160 30-30 open on the check out counter.
I had to look, there were loaded 300 BLK rounds in it.
Asked him how they performed -said great on deer.
Back of box had 2000 fps, H110 20 gn on it.
Said he chrono'd all his reloads.
Just found it interesting, but I don't use H110 (yet).
Did pick up some good rare 22 WMR at a fair price.
 
if i were going to try to push them hard i'd probably look at 1680 or shooters world blackout (do63). folks are pushing 150's beyond 2000 FPS with a nicely compressed load of 1680.


hornady just released (as ammo) a blackout load with 135gr FTX. im waiting on the bullets to be sold as components. If you could push those at 2100 fps or so (should be relatively easy, with multiple powders) that should easily give a 150 yd load, maybe a bit further if you could get em into the 2200 range, but that would take some testing.

hornady's factory load is running 2085 FPS.

Any idea on what powder they were using? I bought a box of the 135 Sierra varmints to tinker with, and they have a meplat opening that looks like a black hole of destruction. Also have some 110 Varmageddons and 125 Speer TNT varmints to play with as well before deer season.

I have the 208 amax going into 0.1" groups at 50, and yes, I have pics to prove it. I didn't believe it until I shot it more than once with similar results. 9.6gns of LIL Gun and a 208amax with a 205m in WW brass

no clue on the powder they used sorry

and its been a busy as [beeep] summer for me so i havent picked up a box to do any load developement with.

i have several calibers with ladders waiting to be shot as is, and two more bullets for the blackout to tinker with as well.
 
Got out and shot again yesterday. Seems like my Ruger American Ranch loves the 208 amax and 220RN sierra. Both of them were launched with 9.6gns of LIL Gun, and they went into .23" and .19" respectively for 3 round groups at 50yds off of a bipod and rear bag. I know that 3rd isn't a large sample size, but I was verifying zero before chasing a few yotes. Will post pics later this evening. 208'208's are a tad bit louder than the 220's. They aren't quite fully subsonic, but for the accuracy thst I am getting, I don't care.
