RCBS AR Neck Sizing Die Set .308win

RCBS AR series loading dies are recommended for users of progressive loading machines.

The set includes a Small Base sizing die and Taper Crimp bullet seating die. This combination facilitates the loading of cartridges for AR-type semi-automatic rifles. The Small Base sizing die reduces the cartridge case at the base more than a standard loading die, improving the reliability of cartridge feeding. The Taper Crimp bullet seating die allows for greater variations in cartridge lengths compared to a standard bullet seating die.
