Winchester Ammo X17W25 Super X17 WSM 25 gr Jacketed Hollow Point (JHP) 50 Bx/10 Cs

The Winchester Super X17 WSM is a purpose-built rimfire round for hunters and precision shooters who demand reliability in a specialized caliber. The 17 Winchester Super Magnum delivers the kind of consistent performance Winchester's Super-X line is known for—tight quality control, dependable ignition, and predictable ballistics. At 25 grains with a jacketed hollow point bullet, this load is designed for varmint hunting and small-game applications where you need controlled expansion and minimal over-penetration. Whether you're working predators at distance or controlling nuisance critters, the X17WSM puts Winchester's reputation for dependability behind every round.

The 25-grain JHP bullet exits the muzzle at 2600 feet per second, generating 375 foot-pounds of energy—sufficient velocity and impact for its intended purpose. The jacketed hollow point design initiates reliable expansion on impact while the jacket maintains structural integrity throughout the cartridge's effective range. Super-X ammunition carries Winchester's legacy of quality control and consistency; you get the same performance round after round, which matters when you're placing precision shots or managing multiple targets across varied terrain.

This is specialist ammunition for a specialized cartridge. The 17 WSM isn't a mainstream caliber, but if you're already running one—whether in a dedicated rifle or modern lever gun—you know the appeal: flat trajectory, minimal recoil, and ballistic characteristics that punish at ranges where standard .22 Magnum rounds fade. Winchester's commitment to Super-X quality means you're not compromising on reliability or consistency just because the caliber is niche.
