Redding Competition Rifle Seating Die .308 Win
The Redding Competition Rifle Seating Die for .308 Win is built for reloaders who refuse to compromise on bullet runout and seating consistency. If you're chasing precision at the bench and your loads demand concentricity that rivals factory ammunition, this die delivers the engineering to get there. Redding engineered this die around a radically tight tolerance seating stem that's precision ground to match bullet diameter exactly, floating on an air column inside the die body. That level of precision eliminates the concentricity issues that plague conventional seating dies—your bullet seats straight, not cocked or tilted.
The system works because the cartridge case and bullet are completely supported and aligned in a close-fitting precision sleeve before seating even begins. This dual-axis support is where the magic happens: tighter tolerances throughout the seating stem assembly mean less runout, tighter velocity spreads, and tighter groups downrange. The micrometer adjustment is calibrated in .001" increments and turns infinitely without detent clicks, so you dial in your exact seating depth and lock it in. A set feature lets you save your preferred depth for your rifle or favorite load, so you're not dialing it in every session.
This is a no-compromises die for serious handloaders and competition shooters building match-grade ammunition. It's not designed for compressed loads, so check your data before committing to a load ladder. If concentricity and runout consistency are your obsession, Redding's competition seating die is the die that sets the standard.

Frequently Asked Questions
What makes this seating die different from a standard die?
The Competition Seating Die uses a precision-ground seating stem that matches bullet diameter exactly and floats on an air column inside the die body. The case and bullet are supported and aligned in a close-fitting sleeve before seating begins, which eliminates the concentricity problems that come with conventional seating dies. The tighter tolerances throughout produce measurably straighter bullet seating.
Is this die compatible with all .308 Win loads?
This die is not recommended for compressed loads. Check your load data before using it with a particular powder and bullet combination.
How does the micrometer work?
The micrometer is calibrated in .001" increments and adjusts infinitely without click detents, giving you precise control over seating depth. It includes a set feature so you can dial in your preferred seating depth for your rifle and lock it in for repeat sessions.
