Hornady Custom Grade Series III 2-Die Set Features The Hornady Custom Grade Series III full length sizer die uses a Zip Spindle with a series of light threads cut into both the spindle and the spindle collet which eliminates slippage and makes tightening the spindle lock simple when dialing in adjustments. This full length sizing approach resizes cases completely which matters for reloaders feeding ammunition through semi-auto or gas-operated .338 ARC platforms where reliable chambering is critical. The set uses the standard 7/8-14 thread pattern so it drops straight into any standard single stage or turret reloading press without modification. Two Die Locking Rings are included letting a reloader lock in a die s exact setting and swap dies in and out of the press without losing that adjustment. The companion seating die carries a floating bullet alignment sleeve and stem that pre-align the bullet and the case before seating improving seating consistency and downstream accuracy. The seating die also applies a crimp to secure the bullet in the case which helps hold bullet position under recoil and feeding in a semi-auto action. The whole set comes packaged in a plastic storage box for organized protected storage on the bench. A shellholder is sold separately so reloaders working up loads for the .338 ARC cartridge get a complete repeatable sizing and seating setup from a trusted reloading name.
