The Frankford Arsenal Platinum Series Hand Deprimer is constructed of robust die cast aluminum and features a (patent pending) Universal Collet System. This system is fully contained and even captures the spent primers in a collection tube so you can dump them later. The Universal Collet System can handle brass from .20 cal all the way up to .338 Lapua. It comes with three (3) different collets for different diameter cases and features an easily removable spent primer catch tube.
