22 LR ammo like Browning’s is the reason why squirrels want nothing to do with us. This is a high-velocity cartridge, with a lightweight 36 grain projectile that enables it to achieve a muzzle velocity of 1,280 fps out of a rifle barrel. The bullet’s thin copper plating does help to minimize the amount of lead residue it’s able to deposit on the bore, and its nose cavity delivers rapid terminal expansion at close-to-mid-range.
This round’s bullet is a little lighter than average, but its hot muzzle velocity indicates that it will reliably cycle semi-automatic rifles and pistols. Browning’s rimfire primers are sensitive enough to take a hint from any firing pin, and their propellant burns clean and evenly to promote reliable ignition and ballistic performance.
