The RCBS ram priming unit for the 50 BMG is a great priming tool for reloaders who want to prime on the upstroke for maximum sensitivity.

The unit works by holding the cartridge case in a shellholder on the top of the press (where the die is typically installed). The press ram is then fitted with a special primer holder (plug assembly). By moving the press ram up, the primer is inserted into the case.
