Winchester Supreme Ammunition 22 Winchester Magnum Rimfire (WMR) 30 Grain Jacketed Hollow Point

Winchester Supreme 22 Winchester Magnum Rimfire ammunition delivers the velocity and terminal performance you need for varmint hunting and small game at distance. This 30-grain jacketed hollow point load generates 2250 fps muzzle velocity and 337 ft-lbs of energy, making it a solid choice for shooters who want reliable expansion and accuracy beyond what standard 22 LR can offer. Whether you're culling coyotes, controlling prairie dogs, or hunting rabbits and squirrels across open country, the WMR's flatter trajectory and harder-hitting payload give you more effective range than rimfire alternatives.

The jacketed hollow point design combines Winchester's manufacturing precision with a bullet construction that's built to expand reliably on impact. This matters when you're taking longer shots where velocity loss is a factor—the heavier payload and jacket help maintain energy downrange and ensure consistent performance on varmints and small game.

Each box contains 50 rounds, giving you a practical quantity for a day at the range or serious predator control work. If you're running a WMR rifle and want ammunition that balances distance capability with lethal terminal ballistics, this Winchester load is worth checking against your rifle's performance data.
