The Hornady 40 S&W and 10mm bullet seating die is built for reloaders who demand consistency and reliability through thousands of rounds. Hornady's Custom Grade New Dimension dies are engineered from select steel with heat treatment that stands up to a lifetime of reloading—the company guarantees they won't wear out or break under normal use. Whether you're loading 40 S&W for duty carry, competition, or range work, or pushing 10mm for hunting and defense, this seating die ensures precise bullet seating every single time.
The seating die incorporates a sliding alignment sleeve that centers the bullet, case mouth, and seating stem before the round enters the die. This alignment geometry is the difference between mediocre groups and tight, consistent loads. You also get a built-in crimp ring—use it for a firm crimp on your rounds, or raise it out of the way if your load doesn't call for one. The choice is yours depending on your application and ammunition specs.
Setup is straightforward thanks to the included double-flat Hornady die lock rings, which grip firmly and won't shift once you've dialed in your seating depth. Everything ships in Hornady's custom plastic die box for safe storage and transport. This is the kind of die that becomes invisible in your reloading routine—it just works, shot after shot, year after year.
