There’s much said, unsubstantiated, about over-penetration of higher-velocity bullets. Just a bit about the whole “defensive-rifle debate”: Some say something like, “5.56 is not a good choice for home defense.” I agree, but not for some reasons commonly given. (Clearly, supersonic Blackout beats it soundly.) 45 ACP is a reliable choice for a defensive round, subsonic Blackout beats it. 45 ACP handgun loading, if we’re going on (the admittedly incomplete) calculated energy figures.
300 Blackout subsonic loads are a little more powerful than a routine. 300 Blackout is plenty powerful, in my estimation, and with radically better shootability than a higher-pressure carbine loading. Most subsonic Blackout ammo uses a bullet in the 200-grain range, and, of course. That’s another debate for others to work though in other articles, but it’s my story and I’m sticking to it. Plus, I’m a believer in “bigger is better” respecting impact effectiveness of a bullet. Subsonic Blackout has a radically milder blast and report than 5.56 or supersonic Blackout. Now, there are some very effective flash suppressors out there, but they don’t take a bit off the noise. In the dark, maybe just up out of bed, and then there’s a blinding fireball and an ear-splitting report, and it’s difficult to recover situational awareness, especially at my age, and even with my rail-mounted light. Good stuff.Ĭivil? I don’t know how many have fired a 5.56 AR-15 carbine inside a room, but it’s sensory overload. Big bullet! My magazines currently hold my most-trusted Nosler 220-grain factory ammo. I built a specialty AR-15 for home defense that I also featured in recent book project, and that was my choice. One reason for its popularity is the supersonic/subsonic option. Pretty much, it’s for those who want a bigger bullet in an AR-15 with a minimum of technical distractions (some call them problems). I like it especially in the shorter guns, and, around here at least, it’s looked on as an effective Whitetail cartridge choice. 300 Blackout, aka: AAC, is a popular cartridge among AR-15 fans.
