"A copper-pointed hollow-point bullet in the classic .22 Long Rifle caliber. This hyper velocity hollow point is great for target shooting and small game hunting. The hollow-point emphasizes expansion over penetration, and its enclosed based offers superior accuracy."
― In-Game Description

The .22LR Hollow-Point Bullet is the only ammunition for the Virant .22LR and Andersson .22LR. The effective range is lower than most rifle rounds, but that comes at the benefit of less bullet drop.

This ammo is available as part of the Weapon Pack 1 DLC.
