Browning Ammunition has announced SUB22, a subsonic .22 Long Rifle ammunition purpose built for use in semi-automatic pistols equipped with suppressors. The company announced the new rimfire load at SHOT Show 2024 in Las Vegas, Nevada, on Thursday, January 25.

The new SUB22 .22 Long Rifle ammo uses a 45-grain black copper-plated lead round-nose bullet and is designed to remain subsonic through pistol-length barrels. In addition, the heavy bullet uses recoil energy to reliably cycle actions.

Browning’s reported muzzle velocity for SUB22 ammo is 1,060 f.p.s. and drops to 1,027 f.p.s. at 25 yards. As for the energy, from the muzzle it’s 112 foot-pounds and goes down to 94 foot-pounds at 25 yards.

More from Browning Ammunition about its new subsonic rimfire load: “Ideal for target shooters and small game hunters using a suppressed pistol, SUB22 ammunition features more reliable functioning in semi-automatic pistols while also achieving maximum noise suppression.”

Optimized to function in suppressed semi-automatic pistols, the new Browning Ammunition SUB22 rimfire load (B194122102) is available now for purchase in 100-round boxes. A quick online search found the new subsonic .22 LR ammo available at Target Sports USA for $12.50 per 100-round box, and $250 for a 2,000-round case.
