Also known as: 17 Win Super Mag, 17 WSM, 17wsm
Winchester released the new .17 Super Magnum in 2012 and it quickly gained a following after shooters witnessed its powerful potential. This rimfire rifle cartridge is a descendent of the .27 nail gun blank, but it was necked down to receive a .17 caliber bullet. Even with the smaller bullet, it delivers stunning accuracy on small game at 300 yard shooting distance. The .17 WSM has laser sharp accuracy and outshines the competing .17 HMR on any range. While the .17 HMR offers internal pressure maxing out at 26,000 psi, the .17 WSM is 50% thicker and delivers internal pressure of 33,000 psi.
