The Speer Jacketed .451 300gr Hollow Point Handgun Bullets, 50 Count (Speer part no. 4485) is a component bullet for handloaders, not loaded ammunition. Speer builds its jacketed handgun bullets with Uni-Cor technology, which produces a uniform jacket. It measures 0.452 inch (11.48 mm) in diameter and weighs 300 grains, and Speer packs 50 to the box. The line is aimed at target shooters who want consistency from one bullet to the next. Match it to published load data and a barrel of the right bore before you build a load.
