The Hornady Custom Grade New Dimension Series IV Rifle 3-Die Set for .375 Winchester (Hornady part no. 546530) equips handloaders with a full sizing-to-seating lineup for this straight-wall lever-action cartridge. The Zip-Spindle design uses a series of light threads cut into the spindle and spindle collet to eliminate slippage, taking the knuckle-busting out of tightening the spindle lock and making seating depth adjustments simple. Wrench flats machined into the Sure-Loc long rings speed up fine-tuning, a headed steel decap pin removes spent primers, and a polished elliptical expander smooths bullet seating without a separate expander station.
