Lee Precision 90965 Deluxe 4-Die Set 40 S&W/10mm Auto

The Lee Precision 90965 Deluxe 4-Die Set delivers comprehensive reloading capability for both 40 S&W and 10mm Auto cartridges in a single package. This complete die set eliminates the need for separate tooling when loading these popular pistol calibers.

What Makes This Different

Unlike standard 3-die sets, this deluxe configuration includes a Factory Crimp Die that applies consistent taper crimp without affecting case length. The dual-caliber compatibility saves bench space and tooling costs compared to purchasing separate die sets. Each die features Lee's precision-ground construction and heat-treated steel components rated for thousands of loading cycles.
