22 round, but certainly louder than a suppressed round that travels 800 fps. Through a suppressed rifle, it's definitely quieter than a standard. I know this speed limit is variable according to temperature, humidity, and distance from sea level, but I can't seem to find out if 800 feet above sea level makes a 1100 fps round sonic or subsonic.Īn obvious answer is to just go shoot it. The Sub-X bullet used in Subsonic Rifle features a lead core. Subsonic Handgun utilizes tried-and-true XTP bullets that expand reliably at subsonic velocities. This avoids the supersonic shockwave or "crack" of a supersonic bullet, which, particularly for suppressed firearms, influences the loudness of the shot." () tell everyone Hornady Subsonic Ammunition designed for accuracy and performance below the speed of sound now comes in both rifle and handgun loads.
#SUBSONIC SPEED BULLET CRACKED#
Super Vel cracked the code of making a subsonic expanding bullet with a 115 gr. But if you reduce the velocity to a subsonic 1100 fps, it produces only 150 foot-pounds. "Subsonic ammunition is ammunition designed to operate at speeds below the speed of sound, which at standard conditions is 1,126 ft/s. At 3250 fps, it produces 1,280 foot-pounds of energy at the muzzle. The idea is for a big bullet going just below supersonic, able to carry a lot of energy downrange at modest velocity. One of the boxes, not labeled "subsonic" had a speed of 1100 fps. The cartridge was originally intended for subsonic use, though a lot of people load it supersonic. When shooting this SUBSONIC round suppressed, the suppressor will muffle the bang, and the round will be very quiet. 22 subsonic brands yesterday to shoot and compare.
