This Underwood .357 Magnum 180gr hard cast flat nose load (Underwood part no. 720) is a 20 rounds-per-box lead bullet round finished in the maker’s Black Cherry coating. Underwood Ammo describes the polymer-based coating as protection against gas cutting that keeps lead from touching the bore and virtually eliminates lead fouling. The flat nose bullet is non-expanding and built for penetration, which Underwood positions for woods defense against animals like wild hogs and black bears. It leaves the barrel at 1400 feet per second with 784 ft-lbs of muzzle energy.

Frequently Asked Questions

Can this load be fired in an ultra-light alloy revolver? Underwood says the ammunition itself is safe for ultra-light alloy revolvers, but the recoil in such light guns can be intense enough to make bullets jump the crimp, so it does not suggest firing this ammunition in them.

Does the Black Cherry coating reduce lead fouling? Underwood says the coating prevents lead-to-bore contact, virtually eliminating lead fouling, and lets you shoot higher velocities without it.

Does this bullet expand? No. It is a hard cast flat nose, a non-expanding bullet that Underwood says is built for penetration.
