The Frankford Arsenal Platinum Series Hand Deprimer is made of robust die cast aluminum and features our (patent pending) Universal Collet System. In just 4 easy steps you can deprime your spent brass by hand. No need to set up your press and reset your dies to deprime a few cases. This system is fully contained. It even captures the spent primers in a collection tube so you can dump them later. Our Universal Collet System can handle brass from .20 cal all the way up to .338 Lapua. This deprimer can even deprime pistol brass, and military crimped primers are easily removed.
