RCBS
The RCBS Matchmaster Competition Seating Die for 6mm BR Remington brings precision bench reloading to competitors and precision shooters who demand consistency round after round. If you're hand-loading match ammunition or developing loads for a 6mm BR competition rifle, a dedicated seating die engineered for concentricity and repeatability makes a measurable difference in group size and velocity consistency. The Matchmaster line represents RCBS's premium platform for serious reloaders who've moved beyond basic die sets.
What sets this seater apart is the engineering that focuses on bullet alignment and consistency. The die houses a free-floating, self-centering bullet seating stem that holds the projectile in perfect concentricity with the case as it's seated. The loading window design—a signature Matchmaster feature—eliminates the fumbling and finger risk of balancing a bullet on a case mouth; instead, you drop the bullet in and let the die's internal sleeve catch and guide it through the seating stroke. For competitors chasing tenths and hundredths, that repeatability matters.
Built from case-hardened steel with precision-drilled and reamed internals, then hand-polished and finished in deep blue, the die is as much a tool you'll reach for year after year as it is a functional piece of reloading equipment. The oversized micrometer adjustment knob features large, legible hash marks and numbers, and the dial action delivers exactly one thousandth of an inch per click—no more, no less. Standard 7/8"-14 threading fits any single-stage or progressive press in your setup.
This is a seating die only, so you'll need a sizing die elsewhere in your reloading sequence. Whether you're prepping match ammunition for a regional 6mm BR competition or fine-tuning loads for a precision rifle, the Matchmaster seater rewards careful handloading with the kind of concentricity and repeatability that shows up on target.

Yes, if your press has a standard 7/8"-14 die head. This includes most single-stage presses (like RCBS Rock Chucker, Hornady Reloader), progressive presses, and bench-mounted units that accept standard reloading dies.
This is a seating die only. You'll also need a sizing die (full-length or neck-size), a reloading press, brass cases, primers, powder, and bullets in 6mm caliber. RCBS offers full 6mm BR die sets if you prefer a matched pair.
The die's internal sleeve catches the bullet as you insert it and holds it centered with the case while the seating stem descends. This alignment control throughout the seating stroke produces more concentric bullets compared to hand-balancing a projectile on a case mouth, where slight tilts can introduce runout.
Yes. The oversized micrometer knob allows precise adjustment in 0.001" increments. You dial the depth you want, and each click delivers exactly that amount of change—essential for fine-tuning bullet seating to match your competition or precision-load specifications.
