Winchester Super-X 22 Winchester Magnum Rimfire ammunition delivers consistent, reliable performance for small-game hunting, varmint control, and precision rimfire shooting. The 40-grain jacketed hollow point load offers the power and accuracy serious .22 WMR shooters expect from a premium rimfire cartridge. Whether you're working prairie dogs at distance, hunting rabbits and squirrels, or running a dedicated WMR rifle at the range, these rounds give you the velocity and bullet construction to get the job done.
The jacketed hollow point bullet design expands on impact, maximizing energy transfer and terminal performance on small game. At 1910 fps muzzle velocity and 324 ft-lbs of muzzle energy, this load strikes a balance between power and the inherent accuracy advantages of the .22 WMR cartridge. Winchester's production standards ensure shot-to-shot consistency, so you get predictable point-of-impact and reliable feeding cycle after cycle.
Each box contains 150 rounds, making it practical for a day at the range or an extended hunting trip. If you shoot a .22 WMR rifle regularly—whether it's a dedicated varmint gun, a backup hunting rifle, or a precision target platform—Winchester Super-X rimfire ammo is built to deliver the performance you're counting on without the complexity or recoil of centerfire alternatives.
