Winchester 22 Hornet ammo in the Super-X line pairs a 45-grain jacketed soft point with a midrange velocity profile engineered for varmint and predator work inside 200 yards. The 22 Hornet is a rimmed, bottleneck centerfire cartridge dating to the 1930s, occupying the niche between rimfire magnums and full-power centerfire rounds. This load exits the muzzle at 2690 feet per second, generating 723 foot-pounds of energy—sufficient for coyote, fox, woodchuck, and prairie dog at typical engagement distances. The jacketed soft point expands on impact while retaining enough core mass to reach vitals on medium-frame varmints. Winchester manufactures this ammunition in the United States, loading each round into reloadable brass cases with non-corrosive Boxer primers.
Load Profile
The 45-grain projectile carries a G1 ballistic coefficient of 0.13, dropping approximately 6 inches at 200 yards when zeroed at 100. Supersonic velocity persists past 300 yards in standard atmospheric conditions. The soft point nose initiates expansion within the first two inches of penetration in ballistic gelatin, creating a wound channel 4–6 inches deep in soft tissue. Brass cases eject cleanly from bolt-action and single-shot rifles chambered in 22 Hornet. Each case accepts standard small-rifle primers during the reloading cycle. This load ships as DOT-regulated hazardous material; verify carrier restrictions before ordering. Fifty-round boxes weigh 0.84 pounds. Federal law requires purchasers to be at least 18 years old for rifle ammunition. Ammunition cannot be shipped to certain states, counties, and cities—review our ammunition shipping restrictions before ordering. Store in a cool, dry location away from heat sources and out of reach of unauthorized users.
