Redding Competition Pistol Seating Die .45 Acp
The Redding Competition Pistol Seating Die for .45 ACP brings match-grade precision to your handgun ammunition reloading. Built for shooters who demand concentricity and consistency in every round, this seating die uses a straight-line design with tolerances tighter than conventional pistol dies. The precision-ground seating stem floats on an air column, eliminating the binding and runout issues that plague standard designs. If you're loading .45 ACP for competition or simply refuse to settle for mediocre ammunition, this die will transform your reloading bench.
What sets Redding's competition design apart is the engineering behind bullet alignment. Both the cartridge case and bullet sit completely supported in a close-fitting precision-ground sleeve before seating even begins. This full support system ensures the bullet enters straight, every time. The seating stem itself is ground to match bullet diameter exactly, which means no sloppy fit, no runout, and no surprises downrange.
Depth adjustment comes via a micrometer calibrated in .001" increments. There are no clicks to hunt through—the micrometer is infinitely adjustable so you dial in your exact seating depth and lock it there. Once you've found your preferred depth, the setting feature lets you mark that position for quick return to your reference load. For handloaders chasing tight groups and consistent performance, this level of adjustment authority is a game-changer.
This die is purpose-built for standard and light to moderate loads. Redding does not recommend using the Competition Seating Die with compressed loads, so factor that into your load development if you're pushing the upper limits of the cartridge.
