Frangible is best for the indoor range. I see you have some rounds made to expand in this article. Done like that, the relatively tiny amount of fast-burning propellant behind that honking .30-caliber bullet gets put to work effectively because the pressure at the gas port is higher. On the downside, this heavy subsonic load will provide little to no expansion, and at handgun velocity (less than 2000fps) will poke holes and crush tissue, likely resulting in a through and through performance. Most subsonic blackout ammo uses a bullet in the 200-grain range, and, of course, .308 diameter. I obviously misread. border-radius: .25rem;

Supersonic .300 Blackout ammunition replicates the ballistics of 7.62x39mm, used by classic AK pattern rifles, but with cartridge dimensions designed with the AR-15 magazine in mind Any bullet thats built to either fragment or readily expand (not the same things but about the same effect) isnt going to get much farther after it meets a solid object. Your discussions, feedback and comments are welcome here as long as they are relevant and insightful. MTYwYjBhYWYzMjliNDdhNjMzYzAyOTM3Njg5MmU1NmYxOGZmYTY2NGU5NjE4 Speed equals energy, so (typically), the faster a bullet can travel, the better. Even the SOF guys will still do 99% of their gunfighting with supersonic rounds.

The 300 AAC BLK is very similar to the Winchester 30-30 in velocity and energy for equally sized bullets. On the other end of the spectrum, use of a supersonic load like the Federal 120g Trophy Copper at 2100fps, will result in projectile expansion to approximately 1.5x the diameter of the bullet, and greater terminal effect. A little edgy. A heavier grain, typically around 180-220 grains, introduces more weight to the projectile, preventing the bullet from exceeding speeds that would break the sound barrier like a supersonic round normally would.

Understatement: .300 Blackout (aka AAC) is a popular cartridge among AR-15 fans. It gives one performance close to that of a .308 Win in a more short action such as the AR's have. No room for a dissertation on gas system operation, but as the gas expands behind the bullet traveling down the barrel bore, an increasingly greater volume is available for the gas to occupy. I let my son shoot my 300BLK AR, subsonic unsuppressed, when I forgot to pack his .22 on one of our trips to the range. A 16" .300 blackout gun running supers and suppressed is still pretty friggin quiet. Honestly, my main interest is in the short, subsonic, suppressed, select fire 300 black. Supersonic 300BLK can have nearly three times the kinetic energy as a subsonic 300BLK. We utilize state of the art 5-axis CNC machines to mill all our .308 and AR-15 80 percent lower receivers to incredibly precise tolerances using premium billet aluminum.

I have an SBR as well in 300BLK which is more fun but when traveling out of state it's easier to just take my 16". No it is NOT worth it unless you are going to go shorter than 10.5".

A bullet traveling at higher speed means more energy that can be transferred to the target upon impact, more effective range, more tolerance to drop and wind drift. I have a feeling I know how most of them will answer, but Ive been wrong a few times in the past. If not, and you need to hit targets at distances past 3-400 yards then opting to shoot 5.56 NATO instead will save yourself some money.

Essentially, all you'd need is an upper receiver with a 300 blackout barrel and you'd be good to go since the 300 blackout magazine is the exact same as normal STANAG/NATO magazines. However, suppressors can't get rid of the sonic boom left in a supersonic bullets wake. Until I started reading forums, I was unaware that .300BLK is expected to not cycle in a 9" unsuppressed rig, so I wanted to make it work properly with the only available ammo. I keep seeing guys new to the 300 BLK on other forums asking about how to open gas ports to reliably run subs without a suppressor and I just don't get it. Because of the lower pressures at the muzzle, and the lack of a supersonic report, shooting "subs" is completely hearing safe and comfortable for the operator and those around them. ZTUzMjk3MjYzOTAzZDg3ZjhhZjFiNTE1NjY0MjJlN2Q3NTc3YjUzNDE4ZWFm The 16" bbl Blackouts do give more velocity for hunting than the short ones do. vertical-align: middle;
