Underwood Ammo .357 Magnum 180-grain Lead Flat Nose ammunition (part no. 720) loads a heavy-for-caliber cast bullet for revolver shooters who want more penetration than a typical 125 or 158-grain .357 load provides. Underwood Ammo casts this 180-grain bullet with a flat meplat that drives a full-diameter, straight-line wound channel, the same working principle behind big-bore hard-cast hunting bullets, just scaled to .357 Magnum. Nickel-plated brass cases resist corrosion through storage and carry. In handgun ammunition for hunters and backcountry carriers who trust a .357, this is a heavier option built for penetration over expansion.

Frequently Asked Questions

Why choose a 180-grain flat nose over a lighter .357 hollow point? The heavier bullet and flat-nose profile trade expansion for deeper, straight-line penetration, which favors hunting and backcountry defense over typical personal defense.
