The Winchester Super-X .325 Winchester Short Magnum (WSM) Jacketed Soft Point (JSP) Power-Point 220-grain 20-round box is a heavy-hitting, high-velocity centerfire rifle cartridge engineered specifically for harvesting large, heavy-boned big game where deep penetration and controlled expansion are required. A common friction point with high-velocity magnum rounds is premature bullet fragmentation or jacket-core separation upon hitting heavy shoulder bones, which drastically reduces penetration depth and compromises vital-zone reach. Winchester eliminates this field bottleneck by packing a heavy-for-caliber 220-grain projectile featuring their classic Power-Point architecture, providing the exceptional sectional density needed to punch straight through thick muscle and dense skeletal structures.
The technical advantage focuses on pairing an exposed soft-nose geometry with a heavily reinforced copper alloy jacket. Launching its massive 220-grain payload at a powerful muzzle velocity of 2,840 FPS, this load commands an incredible 3,939 ft-lbs of muzzle energy. Mechanically, the exposed lead tip initiates immediate deformation under intense hydraulic pressure upon target contact. As the bullet punches inward, strategic notches cut into the mouth of the copper jacket force uniform, symmetrical expansion into a wide-diameter mushroom profile. Beneath the nose, a progressively thickened jacket wall mechanically locks the lead core to prevent premature fragmentation under extreme magnum stress.
Slinging its heavy 220-grain soft point bullet at 2,840 FPS, this load utilizes the unique short, wide case geometry of the WSM family. This fat hull profile places the powder column closer to the primer flash hole, promoting a highly uniform and efficient propellant burn that generates consistent internal pressure curves from a short-action rifle platform. To ensure absolute mechanical reliability under heavy magnum recoil, an integrated mechanical cannelure groove locks the core to the jacket and prevents bullet setback inside the magazine. Built with premium virgin brass cases and ultra-stable primers, this clean-running combination delivers match-grade internal ballistics and glass-smooth mechanical feeding.
Key Benefits
- Exposed Lead Power-Point Nose: Classic soft point configuration initiates immediate terminal deformation and rapid kinetic energy transfer upon target contact.
- Mechanically Notched Jacket: Precision mouth notches control the rate of expansion to guide the bullet into a wide, uniform mushroom profile.
- Heavy 220-Grain Sectional Density: Massively increased projectile weight delivers unmatched bone-breaking penetration and forward momentum on large game.
- Efficient WSM Hull Geometry: Short, wide cartridge case architecture maximizes powder burn uniformity to deliver full magnum velocities in a short-action rifle.
