![]() ![]() To compensate for less velocity, you need more mass. That’s why rounds with long, large-diameter bullets like the. 300 AAC Blackout (which function well in modern sporting arms with a simple upper receiver swap) have become the preferred subsonic centerfire round for sportsmen, as well as for the military and law enforcement. (Note that these long bullets are most accurate when fired from barrels with fast 1:7 twist rates to stabilize them. 22LR ammo reduces velocity to 1050 fps and therefore lowers the decibel level to around 68. Hornady’s 300 BLK subsonic 208-grain A-Max load, for example, delivers 480 foot-pounds of energy from a carbine’s muzzle. 648, at 500 yards it surpasses the energy of a full-power 55-grain.īut because of this long bullet’s incredible ballistic coefficient of. ![]() 223 Rem., and nearly triples that of the. ![]() That’s marginal performance for deer and hogs beyond 50 yards, but it’ll do the job on longer-range varmints where noise is an issue. This type of load is ideal for home defense, where shots are measured in feet and taken in tight confines that exacerbate hearing danger. At the very least, this ammo is a hoot to shoot on the range thanks to its mild recoil and low noise. It’s like shooting a rimfire, but with more punch. Speaking of which, rimfires are where subsonics really shine. 22 LR load delivers around 1200 fps and 140 foot-pounds of energy at the muzzle. ![]()
