The Underwood 10mm Auto 180gr FMJ flat nose (Underwood part no. 241) is a 50 rounds-per-box load with a full metal jacket bullet in a nickel-plated brass case. Underwood Ammo describes FMJ flat nose bullets as non-expanding and powerfully penetrative, built for woods defense against wild hogs and black bears. The flat nose profile helps the bullet keep its nose-forward position as it pierces dense mass, which Underwood says is optimal for maximum penetration. It leaves the barrel at 1300 feet per second with 676 ft-lbs of muzzle energy.
