Hornady Custom Grade 460 S&W /450 Bushmaster Seating Die

The Hornady Custom Grade 460 S&W/450 Bushmaster seating die is built for reloaders who demand precision and durability in their rifle ammunition production. Whether you're loading pistol-caliber rounds in 460 S&W or intermediate rifle cartridges in 450 Bushmaster, this die handles the critical task of bullet seating with the kind of engineering that stands up to thousands of rounds. Hornady's Custom Grade designation means you're working with heat-treated steel designed to last a lifetime—no wearing out, no breaking under normal use.

What sets this seating die apart is the sliding alignment sleeve, which keeps the bullet, case mouth, and seating stem perfectly aligned before the bullet enters the case. That alignment matters: it's the difference between consistent, safe rounds and reloading frustration. The die also includes a built-in crimp ring that you can engage for a roll crimp or raise out of the way if you prefer to seat only. You get the die with Hornady's signature double-flat lock rings already installed—no fiddling with standard rings that slip or rotate—plus a custom plastic die box for organization and storage.

Hornady groups its dies into different price tiers, but construction and quality are consistent across the line. If you're stepping up from basic dies or consolidating your reloading kit, this Custom Grade seater is a no-compromise choice for shooters who care about ammunition quality and die longevity.
