Hornady Custom Grade Series II 3-Die Set for 40 S&W and 10mm Auto – Includes Sizer, Seating, Expander, and Taper Crimp (546534)

The Hornady Custom Grade Series II 3-Die Set for 40 S&W and 10mm Auto is a purpose-built reloading die set designed for pistol handloaders who want to streamline the case-preparation and bullet-seating process. This set combines the three essential dies—full-length sizer, expander, and taper-crimp seater—in one coordinated package, letting you process 40 S&W and 10mm Auto brass efficiently without juggling incompatible components or multiple manufacturers' tooling.

The full-length sizer die features Hornady's titanium ring, which resists galling and extends die life. The expander die is designed to pistol specs, and the taper-crimp seater die handles both seating and taper-crimping in a single pass—a practical time-saver when you're running volume through a progressive or turret press. The set incorporates Hornady's non-slip Zip-Spindle design, a locking mechanism that keeps the die body firmly seated in the turret or adapter without shifting or spinning loose during press cycles, promoting consistent case dimensioning and crimp results shot after shot.

If you're reloading either or both of these popular cartridges and value precision, repeatability, and the confidence that your setup won't slip under pressure, this Hornady set covers the fundamentals. Custom Grade Series II dies are a solid middle ground—they deliver the accuracy and features serious reloaders expect without the premium pricing of boutique options.

Frequently Asked Questions

Will this 40 S&W and 10mm Auto die set work with my single-stage press?

Yes. These dies are standard 7/8"-14 TPI threaded dies that fit any reloading press (single-stage, turret, or progressive) equipped with standard die adapters. The Zip-Spindle locking mechanism works with turrets and die holders.

Can I use these dies to reload both 40 S&W and 10mm Auto in the same session?

The set is chambered for both calibers, but you will need separate brass and primers for each. Swap out your brass and adjust seating depth and crimp as needed between calibers; the dies themselves do not require reconfiguration.

What's included in this set?

The set includes three dies: a full-length sizer die (with titanium ring), a pistol-style expander die, and a taper-crimp seater die. No press, shell holders, or other equipment are included.

What is the Zip-Spindle design and why does it matter?

The Zip-Spindle is Hornady's non-slip locking mechanism that secures the die in the turret or adapter, preventing rotation or drift during pressing. This keeps your dies in precise alignment throughout the reloading session, which is critical for consistent case sizing and crimp results.
