Winchester Super-X Rimfire Ammunition .17 HMR 20 gr. GP 2375 fps 50/ct

Winchester Super-X Rimfire Ammunition is ideal for controlling pests practice or hunting varmints and small game. The bullet seating is precise and the product relies on the proven dependability of Super-X that Winchester has established over the decades.

There is excellent velocity as well as a consistent chamber pressure thanks to the clean burning powder. The risk of barrel fouling is minimized due to the copper alloy jacket. Like other Super-X products from Winchester this rimfire ammunition is designed to provide extreme accuracy and maximize expansion.
