2000 Rounds of .22 LR Ammo by Browning PRO22 – 40gr LRN

A faster bullet has a flatter trajectory. But a slower bullet benefits accuracy in an altogether different way. When a bullet has a muzzle velocity below 1,125 fps, its in-flight velocity necessarily cannot transition from supersonic to subsonic and destabilize the bullet in the process.

Browning’s PRO22 22 LR ammunition exploits that rule of physics so it can deliver the most consistent trajectories possible. This round’s 40 grain bullet only hits 1,085 fps as it bursts out of the muzzle, so it can’t break the sound barrier. A subsonic cartridge is also a quieter cartridge – perfect if you don’t want to make a ruckus while you’re knocking down plinking targets!

This ammo’s lead round nose projectiles are crimped into their cases. Cartridges with such consistently seated bullets all align with the rifling in the exact same way, which only further enhances accuracy. Browning’s target and competition rimfire ammo is loaded in the USA!
