Winchester Super-X Ammunition 22 Winchester Magnum Rimfire (WMR) 25 Grain NTX Polymer Tip Lead-Free

Winchester Super-X ammunition in 22 Winchester Magnum Rimfire (WMR) combines lead-free performance with the inherent accuracy and ballistics that make the 22 WMR a favorite among varmint hunters and small-game shooters. The 25-grain NTX polymer-tip bullet delivers the velocity and energy needed for consistent, reliable kills on prairie dogs, ground squirrels, and other varmints at ranges where centerfire options feel like overkill. Winchester's proprietary lead-free design meets environmental regulations and range requirements without sacrificing the expansion and penetration hunters expect.

The polymer tip design enhances accuracy by reducing drag and promoting consistent flight, while the hollow-point construction ensures reliable expansion on impact. At 2100 fps muzzle velocity, these rounds pack 245 foot-pounds of muzzle energy—enough to get the job done cleanly on small predators and nuisance wildlife without the overkill of magnum centerfire cartridges. Whether you're working prairie dog towns, managing ground squirrel populations on agricultural land, or rounding out your rimfire battery, Winchester's lead-free 22 WMR offers the ballistic performance and ethical consistency serious varmint hunters demand.

Each box contains 50 rounds, making it convenient to stock up or test the load before committing to a full case. The ammunition is loaded to Winchester's exacting standards for reliability and consistency—you'll get the same velocity, point-of-impact, and terminal performance from the first shot to the last.

Frequently Asked Questions

What's the difference between 22 WMR and standard 22 LR for varmint hunting?

The 22 Winchester Magnum Rimfire delivers significantly more velocity and energy than 22 LR—2100 fps versus typically 1200–1500 fps for 22 LR—making it better suited for prairie dogs, ground squirrels, and other varmints at intermediate ranges. The added power reduces wind drift and provides more consistent terminal performance on tougher animals.

Why choose lead-free ammunition for varmint hunting?

Lead-free ammunition is required at many public lands and shooting ranges, and it's increasingly demanded by hunters working in areas where lead ammunition is restricted. Winchester's NTX polymer-tip design performs ballistically like traditional lead ammunition while meeting environmental and regulatory requirements.

Each box contains 50 rounds. A full case includes 2000 rounds across 40 boxes.
