It descended from the .27 caliber nail gun blank by necking down the blank case to take a .17 caliber (4.5 mm) bullet. Initial loadings will be a 20 grain bullet, delivering muzzle velocities around 3000 ft/s .[1]

Winchester, in conjunction with Savage, introduced this cartridge at the 2013 SHOT Show. [2]

The brass case for this round is roughly 50% thicker than the 17 HMR, and the max average internal pressure is 33,000 psi, versus the 17 HMR's 26,000 psi. [3]

Factory ammunition

Currently available is the Winchester Varmint High Velocity Ammunition 17 Winchester Super Magnum in either the 20 & 25 Grain Box of 50. The cartridge at 20 grain = 3000 fps and 25 grain = 2,600 fps.

Firearms

Currently, rifles firing the 17 WSM are the Savage B-Mag bolt action, Ruger Model 77/17, Winchester 1885 Low Wall single shot, the Volquartsen semi-automatic, H-S Precision Pro Series 2000, and the semi-automatic Franklin Armory F-17. The F-17 is the first gas-operated rimfire firearm, designed to handle the higher pressures of this cartridge. [4]
