Winchester Varmint HE 17 WSM 25 grain polymer tip S17W25 ammo uses the heavier of Winchester's two conventional tipped Varmint WSM bullets. Its 25-grain projectile trades some of the 20-grain load's raw muzzle speed for greater bullet mass, creating a separate ballistic choice within the high-energy rimfire lineup.
Rated at 2,600 fps, this cartridge produces approximately 375 foot-pounds of muzzle energy, consistent with Winchester's historical 17 WSM ballistic tables. The 17 Winchester Super Magnum case was developed as a distinct, higher-capacity rimfire design and cannot be fired in a 17 HMR chamber. A 50-round box contains the 25-grain Varmint HE loading for properly chambered rifles.
