I'm shooting a Savage model 16 with 22" ss barrel 1x12 twist. It shoots 39's very well with 27.7g of either of the 4895's, and 27.6g of IMR 8208. So far CFE 223 has been less than stellar in this particular rife, but still looking on it. W748 has done very well also with the 39's.

The following was shot in mid-Dec. 2011. It is slightly over listed max but shoots well in this rifle with no pressure signs. The col for this load was 2.332, but this rifle also shoots the 39's very well with a col of 2.258. Any of these 4 powders shoot pretty regularly in the .3 and .4's and generally run about 3,750 fps. As usual these are only safe in my rifle and may not be in yours.

Great info guys! Keep it coming. Can't wait to see if I can get the 39 BK to shoot well. Along with this same post, it a bullet doesn't shot well for you how much luck do you have with changing powders and your group size getting smaller?

I expect everyone's mileage will vary on your question. My Savage doesn't shoot the 40 vmax very well. It will shoot under moa, but nothing like the 39 sbk. This particular rifle also shoots 32 vmax, 34 Midsouth hp, and 35 Bergers very well. I haven't really seen a powder than it doesn't shoot pretty good with. Some powders are of course faster than others, but I've found a sweet spot with most all of them. So far with CFE 223, I just haven't been able to get it to really settle in consistently and shine in this rifle, but I haven't shot it a whole lot either. CFE 223 has been outstanding in my 22-250 on the other hand.

I killed 14 coyotes last fall with the 32 vmax loaded over 26.9g of A2230 for about 3,950 fps. Only 1 even moved out of their tracks and he only made it about 50 feet. I did lose one with the 32 vmax, but it was operator error. I shot him at 145 yds at night and he was jet black. I hit him too far back and too high and missed the lungs. That's the only one I lost. Unfortunately I would have gladly traded the other 14 for this one black one that got away.

Yea, it was a tough loss. It took me a couple of months to get it out of my mind. I did kill a couple nice coyotes at the end of March using the 39 sbk's and IMR 8208. It just abslutely flattened them both instantly, but I'd still like to have the black one back. I looked for him for 3 days, but it just didn't happen.

I'm sure you'll get a good load worked up. What are you intending to use it for?

I posted a thread with a couple different loads (Varget and TAC powder) awhile back.

.204 range report

This is out of an AR with a 24" Shilen 1:9 twist barrel with a 10x scope from a bench/sandbag front rest. You'd might do better with a bolt rifle as far as accuracy since you might not be limited to mag. length of 2.250", or so.

Well I commend you for putting in a good effort looking for it.

I would like to use it for coyotes and p dog hunting. I figured it would be a good round for p dogs because of its high BC knowning that chances of having perfect conditions are rare.

I was surprised to see BC change drastically by the speed, though.

From Sierra Infinity software for 39 gr. Sierra BK's:

Ballistic Coefficients to Velocity Bounds.
1. 0.287 at 3600 fps. and above.
2. 0.270 from 3400 to 3600 fps.
3. 0.255 from to 3400 fps.
4. 0.236 from 2300 to fps.
5. 0.180 at 2300 fps. and below.

So, I don't have a chrony yet. But, the Hornady Manual says 3600-3700 feet per second with those loads with a Vmax. But, I've heard the book is often way off. So, you just never know until you try a chrony with your ammo.

The other thing is, if you used those coeff. to calculate a drop vs. a different bullet, it's really not that big of a deal as far it's only few inches difference until you get way out there. It's about 5" in the graph below, at 600 Yards between a SBK and a 40 gr. Vmax. After all, your bullet isn't staying at that 3600 fps for very long. Starting at 3600 fps, the Sierra software thinks the Vmax has less drop.

Who knows. Montana in May will be the test, for me.

Or, click this link for a bigger version.

Now I could be completely but I would that any bullet that looses velocity it's BC drops as well. I'm sure on of the more knowledgable members will chime in and correct me or add upon this.

For me I am comparing the 35 gr Berger to a 39 gr BK so there is a big difference especially in wind drift even if the velocity is 200 fps slower than what I'm shooting my 35 gr Berger.

boisblancboy, I don't think you'll be disappointed with the 39 sbk for your intended use. They do have the best bc for bullets that can shoot in the 1x12 twist. Also you won't have any problem launching them between 3,700 and 3,800 fps to be above the listed bc.

Silverfox encouraged me to try them. With reasonable care in shot placement they will kill coyotes like Thor's hammer and make pudding out of pd's. Maybe he'll see this and respond, but in case he doesn't, he always used 35 bergers for coyotes and the 39 sbk for pds, but had to resight his rifle since the two bullets didn't shoot to the same poa. Then one year he didn't have time to resight and just went with the 39 sbks for the coyotes, with good success.

Anyway, he knows a lot more about it than I do, so I went with his suggestion. It gives a good long range load for either species.

Yeah, don't get me wrong. I like the SBK's for targets, so far. In .204:

•Ballistic Coefficient: 0.176 for 35 gr. Bergers
•Ballistic Coefficient: 0.275 for 40 gr. V-Max

I found this online, without any indication of how it drops by speed. I'm not at home, so I can't check Sierra's software as to how the BC drops with a drop in speed. Or, haven't checked how each bullet "bucks the wind"/drift, etc.

But, I guess my point still stands, between any polymer tipped bullet, I'm thinking the BC isn't going to amount to much difference in drift/drop/whatever until you get 100's of YDs away. Sure, 5" inches is a miss on a prarie dog at 600 YDs, but it probably isn't the bullets fault at that point. *wink*

Another good link I've found is at 6mmbr.com with some BC's, drop, drift charts, etc. at the bottom of the article. Shows a different BC for the Bergers than above.

Yeah that's my plan for the most part, 35's for yotes and 39's for dogs. But I won't be afraid to shoot either with either round.

As far as resighting with the scope I have I with just be sure to compensate the correct amount of clicks to get sighted in for 100 yards. I do have tactical turrets which makes it easy.
