Winchester Super-X Rimfire Ammo

Winchester® Super-X® Rimfire Ammo is manufactured to exceedingly high standards with reliable priming, and consistent powder charges and bullet dimensions to yield maximum accuracy and reliability in any firearm you use. Driving a copper-plated lead bullet at high velocity, Super-X 22 ammo cycles flawlessly in semi-autos, as well as any type of firearm action, leaving minimum lead residue in the barrel, feed ramp, or forcing cone. Clean-burning powder and priming also contribute to maintaining firearm actions clean for reliable function. Winchester offers Super-X Rimfire Ammo in a 40-grain, round-nose (RN) bullet, or 37-grain hollow-point (HP). Both types of bullets are well suited for plinking, target practice, and small game hunting—the RN penetrates deeper with minimal damage to edible game; the HP expands to anchor small game and varmints quickly.
