300 Aac Blackout (300blk)

[Expatriot]

• Hornady 110 V-Max, OAL: 2.000
• 110 TSX, 2.015 OAL
• Sierra 155 Palma, 2.150 OAL
• Sierra 220, 2.089 OAL
• Lapua B416 200 grain, 1.960 OAL
• Hornady 150 FMJ-BT 3037, 2.065 OAL
• Nosler Ballistic Tip 125 grain, OAL: 2.085
• Remington AccuTip 125 grain, OAL: 2.085
• Hornady 130 SP #3020, OAL: 2.010
• Sierra H2120 125 ProHunter, OAL: 1.950
• Speer TNT 125 1986, OAL: 2.010

I got a chance to get out and field test a couple of these OAL's. As stated before, some of them are VERY short. I found that with the longer, heavier bullets, this short OAL doesn't cause any problems and so may be a benefit. In my test the 208gr AMAX fed perfectly.

With the shorter, lighter bullets, this was not true. I tried both Sierra 110gr JHP and Hornady 110gr AMAX and have serious feeding issues with both using the short OAL.

The round would end up stovepiped between the bolt and the barrel extension. I'm not exactly certain how this happens but it seems the very short OAL allows the case rim to clear the mag lips before the nse of the bullet is far enough into the chamber to stabilize it and keep it moving into the chamber. Thus the round can flip vertically under pressure from the bolt and we end up with a jam.

I tried this a bunch of times and had prob 7 or 8 jams in about 20 rounds. As soon as I went back to the longer OAL, those jams disappeared.

FWIW this all occurred with a known good PMag.

The 110 Sierra had a large nose cavity so I never tried it. The 110 Vmax is a short bullet.

I am very excited to see that AAC got Remington to team up on the ammo production.

I look forward to seeing this on the shelf of my gun store!

and most likely pay to the tune of $25 a box for what you could load for a mere fraction of that...

By nature of wildcats, anyone who posts in this forum has already resigned themselves to having to reload - but there are tons of people who will now have access to a 300 Fireball-like cartridge. 85% of shooters don't reload at all. And LE/Military cannot load their own ammo.

SWEET! I just need to find where these 85% shoot at, and collect their brass when they leave!

Mr Silvers, I just ordered& received a barrel chambered for 300-221 from Shilen, any guesses on if this will be compatible with the 300blk ammo?

I was told by Shilen this was to be a no turn chamber

And the Corbon is currently $45/box and almost impossible to find.

I think this does nothing but help us out from a factory available ammo standpoint. Plus with the SAAMI specs being standardized, there will hopefully be more helpful reloading information from the major players. The Sierra Manual gets me in the ballpark, but my 10.5" AR barrel is significantly faster than the Thompson barrel they use... and I'm shooting semi-auto!

I do reload, but the wider acceptance increases the likelihood of new (cheaper) bullets being developed for this cartridge! Right now, if you want expanding subs, you have to pay over a buck each and then reload them yourself. it would be nice to have a factory option in the same price range.

Plus if by some longshot miracle, they get widespread military acceptance of this cartridge, then ammo will become very inexpensive!
