Winchester Super-X rimfire ammunition in 17 WSM delivers 25-grain jacketed hollow points at 2600 fps for varmint hunting and target shooting.
Winchester Super-X ammunition in 17 WSM represents a modern approach to rimfire varmint hunting. This cartridge bridges the gap between traditional .22 rimfire and centerfire varmint loads, offering shooters a flat-shooting, hard-hitting option for prairie dogs, coyotes, and other medium-sized game.
The 25-grain jacketed hollow point is engineered to expand reliably on impact, delivering consistent energy transfer and clean, ethical kills. At 2600 fps, this load generates sufficient velocity for effective range and trajectory, making it suitable for both precision shooting and hunting applications.
Winchester's Super-X line represents decades of ammunition manufacturing expertise. The 17 WSM cartridge itself was developed by Winchester to offer shooters a rimfire option with centerfire-like performance—flatter shooting than traditional rimfires with superior downrange energy retention.
