Re: .50 BMG to .416 barrett brass
CH4D has a 5 die set you will need. Give Dave a call at 740-397-7214 He is a real good guy. You will also need a .400 neck ream to thin the neck down from the swaging of the neck. You will need a good press, Imperail sizing wax, anealer, and all of the other regular pieces and parts you would use for a .50 like trimming, primer pocket tools, etc. etc. etc. etc. Have fun.
