RCBS MatchMaster Competition 8x57 Mauser Full Length Bushing Die Set

This is the MatchMaster competition full length bushing die set cut for 8x57 Mauser. The sizing die takes the case body back to specification on every pass, and the neck is handled by an interchangeable bushing rather than a fixed expander.

Choosing the bushing is how you choose neck tension, which puts that variable in the loader's hands instead of the die maker's. That control matters most when the brass on the bench came from more than one maker. Size, prime, charge, seat - the sequence is unchanged, but the neck ends up where you set it.
