Underwood Handgun Ammunition .500 Auto Max 350Gr Jhp 2300 Fps 20/Ct

Underwood Handgun Ammunition in .500 Auto Max delivers serious stopping power for hunters and shooters who demand performance from a big-bore handgun round. Each 350-grain JHP load pushes out at 2,300 feet per second, generating 4,112 foot-pounds of muzzle energy—enough to handle medium to large game and make a statement in self-defense scenarios. If you're running a .500 Auto Max pistol or revolver, this is purpose-built ammunition engineered to work hard when it counts.

The brass construction of the bullet, paired with nickel-plated brass cases, keeps things clean and corrosion-free. All cases are boxer-primed and reloadable, so once you've fired a box, the brass has a second life if you're into handloading. The supersonic velocity ensures reliable expansion and consistent ballistics downrange. Underwood's attention to sectional density (0.2) and ballistic coefficient (G1 0.145) means the projectile is designed to cut through air and resist deflection—important qualities when you're pushing a heavy bullet from a handgun platform.

Lead-core construction provides reliable expansion on game and defensive targets. The round is suppressor-safe, so if you're running a can, you can trust it in that setup. Each box contains 20 rounds of new production, non-corrosive ammunition ready to load and shoot. Built by Underwood Ammo, a respected name in specialty handgun ammunition, this .500 Auto Max load is a solid choice for anyone serious about their big-bore handgun work.
