The Winchester Super-X .22 Hornet 45-grain Jacketed Soft Point (JSP) Brass 50-round box is a classic centerfire rifle cartridge engineered specifically for varmint control, predator hunting, and small game applications where controlled expansion and precise shot placement are required. A common friction point with lightweight, ultra-high-velocity varmint rounds is immediate fragmentation that causes shallow surface wounds rather than deep terminal performance. Winchester resolves this challenge by pairing a traditional 45-grain lead core with a structural copper alloy jacket and an exposed lead tip, managing bullet deformation to balance rapid upset with deep penetration.
The primary technical advantage relies on the mechanical construction of the 45-grain JSP projectile. As the bullet impacts soft tissue or bone, the exposed lead tip initiates rapid, uniform mushrooming, while the surrounding copper alloy jacket reinforces the rear core to prevent fragmentation. Delivering 723 ft-lbs of muzzle energy, the load provides lethal hydrostatic shock on agricultural pests and predators while maintaining a significantly lower muzzle report and lighter recoil signature than larger .223 Rem or .22-250 Rem centerfire platforms.
Launching its 45-grain soft point projectile at 2,690 FPS, this Super-X load yields flat trajectories for small target engagements out to medium ranges. Charged with clean-burning propellants and fitted with non-corrosive Boxer primers, it reduces carbon accumulation to protect precision rifling during extended field sessions. Assembled in precision-drawn, reloadable virgin brass cases, it ensures flawless chambering, consistent headspace, and smooth extraction in both modern bolt-action rifles and vintage .22 Hornet platforms.
Key Benefits
