The RCBS AmmoMaster Single Stage Press has been improved with the installation of the longer support columns and larger toggle block found on RCBS AmmoMaster .50 BMG press. While still set up to use standard 7/8"-14 thread dies and standard shell holders to load most any pistol or rifle caliber, the addition of the .50 BMG 1 1/2" Die Kit(88705) will allow you to load from .25 ACP to .50 BMG.
The .50 BMG 1 1/2" Die Kit contains a Full Length Size Die, Roll Crimp Seat Die, Trim Die, .50 BMG Shell Holder and .50 BMG Ram Priming Unit. The .50 BMG 1 1/2" Press Conversion Kit contains all the parts necessary to modify your AmmoMaster(88701) to accept RCBS's 1 1/2" .50 BMG dies (not included). With the addition of the .50 BMG 1 1/2" Die Kit (88705) you are all set to start loading the powerful .50 Browning Machine Gun!
