Underwood Ammo .44 S&W Special 255-grain Lead Semi-Wadcutter Gas Check ammunition (part no. 737) loads the classic Keith-type bullet profile that made the .44 Special a serious defensive and hunting cartridge long before the .44 Magnum existed. Underwood Ammo casts this 255-grain semi-wadcutter with the wide, sharp-shouldered nose Elmer Keith designed for deep, straight-line penetration, and crimps a gas check to the base to protect it at Underwood’s higher-than-typical velocities. Nickel-plated brass cases resist corrosion and feed smoothly through revolver cylinders. In handgun ammunition for classic big-bore revolvers, this is a load built on a proven, century-old design.

Frequently Asked Questions

What makes a bullet a Keith-type semi-wadcutter? It is the classic wide-shouldered, flat-nosed cast bullet profile developed by Elmer Keith for deep, straight penetration on game and in defensive use.

Why nickel-plated brass instead of standard brass? Nickel plating resists tarnish and corrosion better than bare brass, which helps rounds feed smoothly even after time in a carry gun or range bag.
