That is not true at all. I believe there are two reasons why 9310 is used by some makers: 1 - They think it is better (but they would be incorrect). 2 - They cannot afford the minimum lot size for C158. If anyone does not believe me, call Carpenter and ask to talk to an applications engineer...

AMAX bullets are plastic tipped. Remington 125 OTM bullets are OTM (not tipped). The only tipped ammo that Remington makes is the AccuTip, which has gold plastic tips. Clearly you had some primers pop out - that happened. I don't think Remington-manufactured ammo would do that, but if it...

H2 buffer is the correct buffer to use, but the way. It won't effect pressure but it is best for reliability. We called a meeting of all sales and CS people, and no one remembers having this conversation - nor would it make sense since there is no issue with that. If you think your three...

I am Director of R&D at AAC. True. 300 BLK was designed as supersonic and subsonic. I see it as mostly a supersonic platform - the most reliable and powerful way to shoot 30 caliber from an AR15 that uses normal magazines at full capacity. Here is more info...

No, you cannot trust that report. There is no way that M855 was used.

5744 for subsonic is good.

A1680 is mostly a subsonic powder. You can us it for supersonic, but it will only give the most velocity for bullets over 150 grains. For typical 110-150 grain bullets most people use H110 or W296. You can also use Lil'Gun but it is best to not use a max load for that as it spikes pressure at...

I don't see this as 16 inch ammo vs 20 inch ammo but rather this RD ammo that would probably be better in the 20 inch also than M118LR. Which would you rather fire in a 20 inch? They probably came up with a load optimal for the LMT gas system and tuned it to be accurate in that rifle - and...

We may as well cover the full spectrum of bullet weights: 110 V-Max from a 16 inch 308 is 2857 fps. Hornadyle.com - 110 gr. TAP URBAN® 300 Whisper is 2375 fps. In 300 BLK it can do over 2400 fps at 55,000 psi, but we can go with 2375 to be conservative. Hornady Manufacturing Company ...

The concept of loads being "optimized" for a certain barrel length is a myth and/or marking BS. For example, whatever powder will give the most velocity in a 26 inch barrel will also give the most velocity in a 16 inch barrel. That being said, some loads are better choices than others - and the...

A Sierra 175 MK loaded to 2.245 OAL in Remington brass and with a 7.5 primer with 20.0 grains of A1680 will do 1900 fps in a 16 inch test barrel, and that is at 55,000 psi pressure. That is the same velocity that an M110-C will send the same bullet at 165 yards. What whatever range you...

Let's go with this analogy. Looking up an M-110C - it launches a 175 grain M118-LR at 2495 fps. Ballistic Coefficient Information: .505 @ 2800 fps and above .496 between 2800 and 1800 fps .485 @ 1800 fps and below If we set the same +- 3 inch setting for max point blank range, the...

I am responsible for 300 BLK at AAC and Barnes created these bullets with my input. I don't have to look at their website because I was there for the development every step of the way, but if you want to, here is what their website says: New TAC-TX | Barnes Bullets Barnes took after shooting...

It seems like you were saying it is not effective past 150 yards to me. Here are your past quotes: I suggest the Barnes Black Tip bullet which is launched at 2400 fps, and people report that it expands down to 1300 fps (it was designed for 300 BLK). Then use the load recipe from their...

I said "300 BLK will shoot from 0 to 230 yards with only 3 inches of drop. " and you replied "But I don't agree with your comment about distance and drop. " I posted a chart showing that in fact you can shoot all the way from 0 to 230 yards and never go more than 3 inches high or low. Now you...

I showed how the Barnes bullet expands to more than 50 caliber and penetrates 20 inches at 300 yards from a 9 inch barrel. That seems like it would be effective. The drop at that range is not hard to account for - if you aim for the head you will hit the chest. Shooting at much farther ranges is...

Gun / Ammunition : 300 AAC Blackout Bullet : .308, 110, Barnes Black Tip Bullet weight : 110 grains or 7.13 Grams Muzzle velocity : 2400 fps Crosswind speed : 10 Mph Ballistic Coefficient(s) (G1): C1=0.290@V>2800 fps; C2=0.290@V>2000 fps; C3=0.290@V>1350 fps...

There is no accuracy issue with that twist rate. This is my 1/7 twist 9 inch upper. I shot it with the AAC suppressor and factory ammo at 100 yards using an Aimpoint Micro and no magnifier. This is not just my best group - it is my only group with this setup. I shot it once, and this was the...

300 BLK will shoot from 0 to 230 yards with only 3 inches of drop. Saying that it is only great to 100-125 yards is ridiculous, unless you are shooting it from a 4 inch barrel - in which case I would agree.

The bullets fully expand to close to 0.60 caliber even at 300 yards and even from a 9 inch barrel! If you think guessing about 9 inches is hard (though not really a guess since we know it is 9 inches), you should try archery. At 300 yards, 300 BLK it will make a 50 caliber hole 24 inches...
