Winchester Super-X 22LR Ammo For Sale

Winchester Super-X 22 LR is one of the most recognizable rimfire loads in American shooting - a 40 grain copper-plated round nose that has been the default 22 LR for plinking, small-game hunting, and entry-level competition since the Super-X line launched in 1922. For 22 owners running anything from a Ruger 10/22 to a Marlin bolt-action to a single-shot kid's rifle, Super-X is the shell most of them learned to shoot with and the one they keep stocked in the safe.

The 40gr Super-X load leaves the muzzle at roughly 1,300 feet per second, putting it in the high-velocity 22 LR category - flat enough for inside-50-yard small-game work and consistent enough for casual target shooting. Where match-grade 22 LR optimizes for X-ring scoring at the cost of higher per-round price, Super-X aims at the middle: better than bargain bulk-pack rimfire, well short of premium match pricing.

Why shooters choose Winchester Super-X 22 LR

• Century-tested: the Super-X line is American rimfire's longest-running default.
• High-velocity 40gr profile: flat-shooting load for plinking and small-game hunting.
• Universal compatibility: reliable in autoloading and bolt-action 22 platforms.
• Mid-tier price: better than bulk-pack rimfire, well under match-grade 22 LR.
