The low-priced Lee 50 BMG Ram Prime is manufactured from quality materials in the United States. This ram prime is made specifically for use with large series .50 BMG and goes with the Classic Cast Press. The manufacturer notes that the shell holder priming holes of other manufacturers may be too small to fit the diameter of this ram prime.

Included with this particular prime is a punch. With this the prime is made to work on the press upstroke as opposed to the down stroke producing more leverage along with a more positive seating feel.
