The Redding 300 Remington Ultra Magnum bushing full length die set is purpose-built for handloaders who demand precision and consistency in rifle ammunition reloading. This two-die set combines Redding's Type S bushing full sizing die with a competition bullet seating die, giving you the control you need to produce match-grade 300 RUM ammunition. Whether you're loading for long-range hunting, precision rifle competition, or load development, this set lets you dial in exact case neck sizing and bullet seating concentricity without compromise.
The Type S bushing sizing die is where this set earns its reputation. Full length resizing maintains your cases' dimensions throughout their loading life, and the interchangeable bushing system puts you in charge of how much you resize the case neck. That's the key difference between a generic die set and one built for precision: you can adjust neck tension to match your rifle's chamber tolerances and your shooting goals, rather than accepting a one-size-fits-all approach. No guessing, no settling.
The competition bullet seating die features a micrometer calibrated in .001" increments, so you're setting bullet depth with real precision. The floating seating stem helps eliminate concentricity issues that can throw off accuracy—a feature that matters when every round counts. Together, these tools let you build ammo that shoots true, load after load.
