Winchester Ammo Big Bore 10mm Auto 200gr Semi Jacketed Hollow Point 20 Rd - Box or Case

The Winchester Big Bore is a heavy-bullet hunting load chambered in 10mm Auto. Part of Winchester's hunting-focused handgun ammunition lineup, it drives a 200 grain Semi Jacketed Hollow Point at 1175 fps, producing 613 ft lbs of muzzle energy from a standard pressure envelope.

The Semi Jacketed Hollow Point design is engineered for deep penetration. The jacket controls and delays expansion so the bullet drives deep before opening up, which achieves massive shock and produces a lethal wound. That combination of weight, velocity, and controlled expansion is what makes this load a serious choice for hunters who rely on the 10mm Auto platform.

Each round is loaded in a reloadable brass case, giving handloaders quality brass to reformulate custom 10mm Auto hunting and defensive loads. Whether stocked for a hunt, a backup handgun in thick country, or simply kept on the reloading bench, Winchester Big Bore delivers the deep penetration and controlled expansion the 10mm Auto was designed for.
