The Redding Series C seating die is engineered for seating bullets in straight-wall cases chambered for .450 Bushmaster. It uses a molded design with a separate rear punch to seat the case body to the shoulder, a method favored for consistent seating of military and target bullets. The die allows the expander ball to be moved to the rear when a crimp is required, and positions both the pilot and seating stem on the same side of the case neck to promote smooth, concentric cycling. Reduced neck friction permits seating toward the limit of the case neck rather than drawing the bullet through the full case length.
