Redding Full Length Die Set For Bottleneck Cases .450 Bushmaster
The Redding Full Length Die Set for Bottleneck Cases in .450 Bushmaster gives you everything needed to reload this potent straight-wall cartridge on any standard press. This two-die set pairs a full-length resizing die with a seating die, engineered to handle the unique demands of the .450 Bushmaster—a cartridge that demands precision if you're chasing deer or hog at hunting distance. Whether you're a newcomer to reloading or you've been handloading for years, a quality die set from a maker like Redding is the foundation of consistent, safe ammunition.
Redding manufactures dies using premium alloy steels and production tolerances tight enough to ensure your ammunition chambers reliably in any SAAMI-spec rifle, regardless of action type. Each die is heat-treated in controlled furnaces and hand-polished before inspection, then ultrasonically cleaned—the kind of attention that translates into smooth feeding, accurate seating, and dies that last decades. The included die box doubles as a loading block and cartridge storage, and you get a spare decapping pin and hex wrench in the box, plus a slot to stash your shellholder.
The full-length resizing die features a decapping rod assembly and neck expander button to resize brass to factory dimensions. The seating die incorporates a built-in bullet guide, crimp ring, and the correct seating plug for the .450 Bushmaster. Both dies use the standard 7/8-14 thread, so they'll work with virtually any modern reloading press.
