What Makes This Different

Hornady's Custom Grade dies feature heat-treated steel construction with precision-ground surfaces that maintain dimensional accuracy over thousands of reloading cycles. The elliptical expander reduces case neck tension variations compared to standard ball expanders, while the sliding sleeve bullet seater prevents bullet deformation during the seating process. These dies produce ammunition that matches factory specifications for headspace and overall cartridge length.

The full-length sizing die returns fired cases to SAAMI specifications, ensuring reliable chambering in any 300 Win Mag rifle. Competition shooters benefit from the consistent neck tension and bullet seating depth, while hunters appreciate the reliable feeding and accuracy potential of properly sized ammunition.
