I am trying out SK Long Range Match. SK is the German made rimfire brand now owned by Lapua of Finland. SK is one of the few choices for competition grade, match ammo that I’ve found in California. For the test, I’m comparing it to CCI Standard Velocity, which many consider the best overall “bulk” rimfire ammo for bolt-action rifles and bullseye pistols.
I am testing various 22LR rimfire ammunition at 100 yards to determine which produces the tightest groups in my CZ 457 rifle. My rifle build is a factory-stock CZ 457 VPC, topped with an Area 419 Picatinny rail, and a Discovery Optics XED 6-36×56 scope (their top-tier long-range optic with Japanese eXtra Low Dispersion ED glass).
After shooting 20 rounds of each, SK certainly outperformed CCI but its also about 4x the price.
