The Universal Hand Priming tool features a convenient universal shellholder that accepts virtually any case from 32 ACP to 45-70 Government, eliminating the hassle and expense of using shellholders. Also features a patented safety gate that isolates the primer seating operation from the primer supply - virtually eliminating the possibility of tray detonation. The removable primer tray correctly positions the primers for use and will fit any manufacturers' primer packaging. For use with large and small rifle or handgun primers. Lifetime warranty from RCBS.
