This all-American round sports the 22 LR’s most common bullet. The 40 grain lead round nose is designed solely for affordable accuracy. It won’t expand after impact, but it will achieve a high 1,255 fps muzzle velocity out of a rifle barrel and proceed to run across a flat trajectory. (Browning reports this ammo’s handgun muzzle velocity at 1,060 fps, i.e. subsonic.) The bullet is additionally black oxide coated for improved functionality in semi-automatic firearms.
The LRN projectile lacks any copper plating that would have reduced lead fouling. But Browning’s concentric and supple brass cases do seal off the chamber effectively during ignition, and their propellant combusts without leaving too much residue in its wake. Hey – if you don’t want to clean your firearm, don’t fire it!
