Universal Hand Priming Tool eliminates that problem. The UHPT features a Universal Shell Holder system that will accept cases from .32 ACP to .45-70 Government. Simply install the appropriate size screw-in primer plug, fill the primer tray, insert it into the tool and you are off and priming. The ergonomic grip is comfortable to use by right or left handed users. The Primer Seating Safety Gate isolates the primer being inserted from the primer supply in the tray.
