The Hornady 40 S&W/10mm Full-Length Sizing Die (Hornady part no. 046534) is a full-length sizing die for 40 S&W/10mm brass. Made by Hornady, a longtime staple on the reloading bench of handloaders who work up their own precision ammunition. This die is machined to fit standard reloading press threads and drops straight into your existing die set for 40 S&W/10mm cases. Handloaders sizing, expanding, seating, or crimping 40 S&W/10mm brass for hunting, competition, or range practice rely on dies like this one for round-to-round consistency that factory ammunition can’t always match. It’s built for the reloading bench, not the range bag, and belongs in the toolbox of anyone loading their own 40 S&W/10mm ammunition.
