17 WSM Ammo For Sale

.17 Winchester Super Magnum (.17 WSM) is the highest-performance factory rimfire cartridge on the market - a .27 caliber nail-driver based on a necked-down .27 caliber industrial nail-gun case. Launched by Winchester in 2013, .17 WSM pushes a 20gr or 25gr polymer-tipped bullet at velocities approaching 3,000 feet per second, putting it in centerfire varmint-cartridge territory while keeping the cost and report of a rimfire.

For varmint shooters, .17 WSM occupies a unique niche above .17 HMR and .22 WMR but below entry-level centerfires like .22 Hornet and .204 Ruger. The cartridge delivers flat-shooting performance out to 200+ yards on prairie dogs, ground squirrels, and coyote-sized game, with explosive terminal effect typical of the .17 caliber polymer-tip family.

Why shooters choose .17 WSM

• Top-tier rimfire velocity: 3,000 fps from a 20gr bullet outclasses every other rimfire option.
• Flat trajectory: usable on varmints out to 200+ yards.
• Cheap to shoot relative to centerfire: rimfire pricing with .22-250-class performance inside 200 yards.
• Specialized varmint role: built specifically for prairie dog, ground squirrel, and similar small game.
