223 Rem., and nearly triples that of the. 648, at 500 yards it surpasses the energy of a full-power 55-grain. But because of this long bullet’s incredible ballistic coefficient of. Hornady’s 300 BLK subsonic 208-grain A-Max load, for example, delivers 480 foot-pounds of energy from a carbine’s muzzle. 22LR ammo reduces velocity to 1050 fps and therefore lowers the decibel level to around 68. (Note that these long bullets are most accurate when fired from barrels with fast 1:7 twist rates to stabilize them. 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. That’s why rounds with long, large-diameter bullets like the.

To compensate for less velocity, you need more mass. The other is because a lack of energy going forward equals a lack of energy going backward-and so they can fail to cycle semiautomatic rifle actions. This is one reason why you rarely see subsonic. 22 LR-the difference between a load for deer and a load for prairie dogs. But if you reduce the velocity to a subsonic 1100 fps, it produces only 150 foot-pounds.

Traveling at 3250 feet per second out of the muzzle, it produces 1,280 foot-pounds of energy. Since energy is the product of mass times velocity squared, a slower bullet has exponentially less energy than a faster one of the same weight. But there’s still the question of performance, which is significantly hampered by going subsonic. Quietest of all is to use a suppressor in tandem with subsonic ammunition, which can reduce the sound of gunfire to a whimper in the rain. It’s just one way to mitigate the noise.Īnother way is to buy a suppressor (legal in 39 states), which will greatly muffle those escaping gases. So while subsonic ammo does eliminate the downrange crack, and does reduce the bang at the muzzle somewhat due to its lower velocity, it won’t make your centerfire rifle sound like mouse feet on felt. Walney down the road into a fit of agita. It’s the latter bang that causes hearing damage, reveals shooters’ positions, scares game, and works Mrs. Most of the noise inherent with shooting a rifle, however, comes not from the bullet breaking the sound barrier, but from expanding gases rapidly escaping the rifle’s bore.

When a moving object, such as a bullet, breaks that threshold, there is an audible shock wave that sounds like the crack of a bullwhip. Still, subsonic ammo does fill an important niche for many hunters and shooters.Īt sea level, the speed of sound is roughly 1127 feet per second. Your rifle will still go bang, and none of this quieter ammo is powerful enough for hunting big game much past slingshot range.

Subsonic cartridges do produce less noise than full-velocity rounds, but there’s no free lunch-as usual. The label on the ammo box says subsonic, so this stuff won’t spook every deer in the county like your earth-shattering.
