7X57 Mauser Collet Die Set

Lee 7X57 Mauser Collet Die Set includes a Collet Die that uses a collet to squeeze a mandrel creating a precisely aligned case neck while reducing run out, Dead Length Bullet Seater Die, Shell Holder, Powder Dipper and Instructions/Load Data.

**Note:  The 7x57 Rimmed Mauser uses the standard 7x57 dies, but will need a different shell holder to hold the case. The Rimmed cases would use a #5 Shell Holder instead of the #2 supplied in the die sets.
