The Hornady 40 S&W/10mm Crimp Seating Die (Hornady part no. 044178) is a crimp seating 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.

Key Specifications

• 40 S&W/10mm is the cartridge this die is machined to size, expand, seat, or crimp.

• Hardened tool-steel body resists wear from repeated press strokes for a long service life on the bench.

Frequently Asked Questions

What does this crimp seating die do? Seats the bullet and applies a crimp to the case mouth in one station, saving a step on turret and progressive presses.

Do I still need a separate crimp die? No, this die seats the bullet and applies the crimp together in one station, which is why it’s a popular choice on presses with limited die stations.
