17 WIN SUPER MAG
The 17 Winchester Super Magnum (aka 17 WSM) is not to be confused with the 17 HMR. The 17 WSM has very different dimensions, not to mention a centerfire primer instead of a rimfire one. This dedicated varmint slayer is usually loaded with bullets ranging in weight from 15 to 25 grains. Even its heaviest projectile achieves a muzzle velocity higher than Mach 2, which spells a laser-like trajectory that ends in varmint doom.
