.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. Initial loadings were with a 20 grain bullet, delivering muzzle velocities around 3000 ft/s .^[2]

Development

Winchester, in conjunction with Savage, introduced this cartridge at the 2013 SHOT Show. ^[3]

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. ^[4]

Factory ammunition is available from Winchester, Federal American Eagle, and more recently Hornady.

Hornady 17 Win Super Mag and Federal Ammunition American Eagle® 17 Win. Super Magnum cartridges are currently only available with 20 grain polymer-tipped projectiles rated @3000 FPS at the muzzle.
