Winchester Ammo Big Bore 357 Mag 158gr Semi Jacketed Hollow Point 20 Rd - Box or Case

The Winchester Ammo Big Bore line is Winchester's classic hunting-grade 357 Magnum load, designed to put serious energy on target from revolvers and lever-action rifles alike. Loaded with a heavy 158 grain Semi Jacketed Hollow Point (SJHP) bullet, this round is built for big-game hunting and defensive field use where expansion and penetration matter most.

At the muzzle this load drives the SJHP out of the barrel at 1460 fps, producing 748 ft lbs of energy, numbers that put the Big Bore 158 grain squarely in the upper tier of 357 Magnum hunting loads. The semi-jacketed hollow point is engineered to hold together on impact, drive deep, and deliver consistent expansion on thick-skinned game, making it a long-trusted choice for handgun hunters pursuing whitetail, hog, and similar medium-to-large game.

Components are loaded into brass casings for reliable feeding, extraction, and corrosion resistance. Winchester builds these rounds as New current-production ammunition, and they are packaged in 20-round boxes that stack cleanly into a 200-round case for bulk orders. Whether you are topping off lever-action magazines for a deer hunt or stowing a few boxes in your field bag for revolver backup, the Winchester Big Bore load is a no-nonsense option for shooters who want dependable performance from the 357 Magnum cartridge.
