The Redding 300 WSM Competition Bushing Neck Die Set is a precision reloading die system built for shooters who demand consistency and accuracy in their handloads. This three-piece set—featuring a competition bushing neck sizing die, body die, and competition bullet seater—gives competitive shooters and serious handloaders the tool set to produce match-grade ammunition. Each component is engineered to minimize runout and maximize case concentricity, which directly translates to tighter groups downrange.
The Competition Bushing Neck Sizing Die is the heart of this system. It uses a fully supported, sliding sleeve design that completely encloses the case neck before sizing begins. As the case rises, the bushing self-centers on the neck while maintaining precise alignment—much like a firing pin guided by the die's internal geometry. The micrometer adjustment lets you dial in exact neck length control, so you're sizing only what needs sizing and preserving case life. The Body Die handles full-length resizing and shoulder bump independently, without disturbing your carefully sized neck. The Competition Bullet Seater features a floating stem design with tolerances tight enough that the seating stem actually floats within its guide—delivering repeatable, concentric bullet seating that serious competitors depend on.
This die set is purpose-built for the 300 WSM cartridge and works with standard reloading presses. Both the neck die and seater feature micrometer adjustments for fine-tuning. Note that bushings and shellholders are sold separately, so you'll need to source those to complete your setup.
