Experience the pinnacle of rimfire performance with Winchester Varmint HE 17 Winchester Super Magnum ammunition. This revolutionary cartridge delivers unmatched velocity, energy, and trajectory in the rimfire world, making it the fastest commercially available rimfire cartridge ever produced.
The 25 grain polymer tipped bullet achieves a blistering 2,600 feet per second muzzle velocity, generating 375 foot-pounds of energy at the muzzle. This exceptional ballistic performance translates to flatter trajectories, reduced wind drift, and devastating terminal effects on varmints at extended ranges. Whether you're targeting prairie dogs, ground squirrels, or predators, the 17 WSM delivers the speed and accuracy serious varmint hunters demand.
Built on Winchester's innovative design using a modified .27 caliber nail gun blank case necked down to .17 caliber, this ammunition operates at higher pressures than traditional rimfire cartridges while maintaining the affordability and convenience of rimfire shooting. The brass casing and precision-engineered polymer tip ensure consistent ignition and reliable feeding in bolt-action rifles chambered for this high-performance round.
