Subsonic factory ammunition abounds for recreational shooting and defensive use. It will reliably cycle AR actions, and as such, suppressed ARs and the 300 BLK go together like corn feeders and Texas. 45 ACP handgun, but with a far more aerodynamic bullet. When loaded with 200-or-so-grain bullets moving at about 1,000 feet per second, it is subsonic, with ballistics similar to a. The 300 BLK is intended to be a defensive cartridge, but it serves dual roles. All you need to do to change your 5.56 to an 300 BLK is swap barrels, though most shooters opt for a separate upper receiver. It works in standard 5.56 AR magazines and with AR-15 bolts. But its versatility and performance is surprising. It’s short and stubby, with a bullet that seems too big for the case. The Whisper was based on the 221 Fireball case, but most describe the 300 BLK as being a 223 case, necked up to. The cartridge was commercially introduced in 2010 by Advanced Armament Corporation, but the cartridge had actually been around since the early 1990s as the 300 Whisper, a wildcat developed by J.D. I personally have 3 short pistols, (7.5, 9, 10.5") and have not had the unreliability you state at all.Next to the original 5.56mm NATO/223, the 300 AAC Blackout (BLK for short) is the most popular chambering for the AR-15 platform, and, as a result, manufacturers now pump out a wide variety of 300 Blackout ammo. As far as terminal ballistics, most shots in home will be under 60 feet so at home protection or even 75 yard hog hunting, where does terminal ballistics come in?Īlso, you stated above the 300 BO is hard to run reliably in short packages but the exact design is for it to burn almost all propellant out of short barrels. User experience on ammo from manufacturers that state their product does not over penetrate and dumps all the energy in the target is what I am looking for. While I agree with you that the 5.56 would be better because of the way that the round breaks up as designed to, but even suppressed 11.5" barreled 5.56 is still pretty loud indoors.Ī suppressed 9" Sig Virtus pistol 300 Blk with a 1-5 twist rate is one of the home defense guns in and the other is a suppressed 7.5" AR pistol 300 Blk with 1-7 twist. The reason for the thread was to get opinions of 300 BO ammo that tends to dump all its energy upon impact. Not exactly worried about stray shots as much as over penetration. Suppressed supersonic isn’t Hollywood quiet, but I’ll take the somewhat louder shots for increased terminal performance. I’d prefer lighter supersonic ammo in 300 BLK, even when running suppressed, as opposed to subsonic which will tend to act more like an overly long pistol projectile. There’s not a lot of research done yet but some people have reported good results on deer with “varmint” projectiles, which tend to have pretty good expansion at 300BLK velocities, vs the rapid fragmentation at 308 velocities. Many other BLK rounds use projectiles intended for 308 and don’t expand nearly enough and tend to penetrate way more than 18”. The round I keep hearing is a good one is the TAC-X. It loses a LOT of energy after going through just a couple layers of drywall (to the point that if your shot goes through 2-3 of your interior walls, it is unlikely to penetrate the neighbor’s wall), and with proper ammo selection has fantastic terminal performance.ĭownside over 300BLK is how loud it is unsuppressed and is harder to run reliably in shorter packages.ģ00BLK just doesn’t have as much selection for good “duty” ammo. Honestly if over penetration and containing stray shots is the primary concern, 223/556 is just about the best round there is. Frangible ammo also has horrible terminal ballistics. I also have one 20 round mag of Hornady sub-x because im too cheap to buy some of the solid copper expanding subsonics (like the maker REX) but its not the primary go to ammo ill choose. It seems to do well in gel, was a resonable price for me to buy a couple hundred rounds and experiment with it. I have 110 grain Vmax Hornady black ammo. Youll have to look at any ballistics gel testing that is done on the ammo you are considering and deem if that is acceptable to you. just that you are looking for a magic bullet and it doesnt likely exist. Im not trying to tell you that you're wrong in wanting. if you only hit soft tissue or an especially thin target youll increase your risk of over penetrationīy selecting ammo that seeks to mitigate this by reducing penetration you risk not getting enough penetration on a especially thick target or hitting hard tissues/bone Penetration through a "soft" (read human) target is a bit unpredictable IMO. TL:DR - Im just some rando on the internet, do what you want. Manufacturers make ammo that they advertise doesn't over penetrate.
