Lapua X-Act .22 LR 40gr Lead Round Nose Ammunition

Lapua X-Act .22 LR 40-grain lead round nose ammunition (brand part no. LU420161) is Lapua’s top competition rimfire offering, built in Finland for shooters who compete at the level where ammunition consistency decides matches. Lapua has spent decades refining X-Act specifically for Olympic and world-class biathlon and smallbore competition, holding tolerances far tighter than any hunting or plinking load requires. The 40-grain lead round nose bullet is built for uniform velocity and predictable feeding rather than expansion, so every round in the box behaves identically to the last. Boxed 50 to a container, this is serious rimfire ammunition for shooters who need match-grade consistency, not just accuracy on a good day.
