We carry factory ammunition from several manufacturers. It is now available from Winchester, Federal American Eagle, and more recently Hornady.

The .17 Winchester Super Magnum, is a rimfire rifle cartridge developed by the ammunition company Winchester in 2012. It descended from the .27 caliber nail gun blank by necking down the blank case to take a .17 caliber (4.5 mm) bullet. loaded with a 20 grain bullet, it  delivers muzzle velocities around 3000 ft/s.

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.

The 17 WSM is a very widely used rimfire ammunition for varmint control because of its flat trajectory, devastating velocity and it's price point.
