This is the RCBS Ammomaster 50 BMG Pack. It include the Massive 50 BMG Press, Shell holder and all 3 dies. This is NIB never used in original packaging. I was going to buy a 50 BMG rile but have changed my mind. Here is the link to RCBS: https://shop.rcbs.com/ammomaster-50-bmg-pack/
This is truly an amazing press. Current retail is almost $900. Local pickup or user pays shipping.
