SK Semi-Auto Rifle Ammunition 22 Long Rifle 40 Grain Lead Round Nose

SK Semi-Auto .22 LR ammunition in 40-grain lead round nose is built for shooters who want reliable, accurate rimfire rounds that cycle cleanly through modern autoloading .22 rifles. Whether you're running a Ruger 10/22, an AR-platform .22 upper, a Marlin 60, or any other semi-auto .22, this round delivers the dependable function and precision you need for plinking, small-game hunting, or high-volume range sessions. The 40-grain lead round nose projectile strikes a balance between velocity and accuracy while keeping costs reasonable for high-round-count shooting.

Semi-auto .22 rifles demand ammunition that feeds reliably and cycles the action without hiccups—and that's exactly where SK Semi-Auto rounds shine. The round nose profile and consistent quality control help ensure smooth feeding and minimal jamming, so you can focus on hitting your target instead of clearing the chamber. These are the kinds of rounds that make you want to grab your .22 and spend an afternoon at the range.

Lead round nose is a classic choice for .22 LR shooters because it shoots clean, groups well, and won't break the bank when you're burning through multiple magazines. If you run semi-auto .22s and haven't tried SK's dedicated semi-auto loading, they're worth a serious look—especially if you've experienced feeding issues with other budget rounds.
