The Redding 300 Remington SAUM bushing full length die set gives precision reloaders the tools to consistently produce match-grade ammunition for this popular magnum cartridge. Built around Redding's Type S bushing system, this two-die set combines a full-length sizing die with a dedicated competition seating die, letting you dial in exact neck tension and bullet seating with repeatable accuracy. If you're loading for a 300 SAUM rifle and demand tight tolerances, this set addresses the real-world challenge of keeping case necks concentric while maintaining the neck control that separates good ammo from great ammo.

The Type S full-length sizing die is the workhorse here. Instead of a fixed sizing bushing, you get interchangeable bushings that let you control how much you resize the case neck—crucial for preserving case life and tuning your setup to your rifle's chamber and the bullets you're seating. This approach is standard among match reloaders and benchrest shooters who understand that one-size-fits-all sizing often leaves performance on the table.

The Competition seating die handles the precision end. A micrometer adjustment calibrated in .001-inch increments gives you fine control over seating depth, while the floating seating stem is engineered to reduce run-out and keep bullets centered in the case neck. For 300 SAUM loads destined for long-range hunting or precision rifle work, that concentricity matters—it's the difference between a load that groups and one that doesn't.
