THIS AMMUNITION CANNOT CYCLE A SEMI-AUTOMATIC FIREARM. ITS CHAMBER PRESSURE ISN’T PEPPY ENOUGH.

Your suppressor doesn’t want supersonic ammo. It wants subsonic ammo, because its report doesn’t include the jarring blast wave that it is not engineered to assuage.

More specifically, your suppressor wants this 5.56x45 ammunition by Armscor! Its bullet is heavy at 77 grains, and its propellant charge is a great deal weaker than standard. The bullet gains a mere 1,100 fps muzzle velocity out of a 18” barrel (speed of sound: ~1,125 fps), and will cruise even slower out of a shorter tube!

Hornady’s open tip match is a fine piece of ballistic technology. Concentric jacket. Match profile. Boat tail. Zero capacity for terminal expansion, and pretty much inaccurate past 100 yards owing to its lethargic muzzle velocity, but reasonably accurate within a realistic range.
