The RCBS Matchmaster Competition Seating Die in .22-250 Remington (RCBS part no. 10640) combines the best features of RCBS’s Gold Medal and Competition die lines into one seating die built for handloaders chasing single-digit extreme spreads. Each die is machined from case-hardened steel, hand-polished inside and out, and finished in a deep blued finish to match the fit and finish of a fine firearm. It is a dedicated bullet seating die, meant to pair with your existing sizing die for this cartridge.

Key Specifications

• Chambered specifically for .22-250 Remington, sized to that cartridge’s bullet and case dimensions.
• Body is machined from case-hardened steel, then hand-polished for smooth, consistent operation stroke after stroke.
• Finished with a deep blued finish, the same treatment used on premium firearm parts.
• Adjusts via a large oversized micrometer knob with bold letters and hash marks, calibrated in 0.001 inch increments for repeatable seating depth.
• Features an exclusive loading window with bullet retention, so you drop the bullet in and run the press instead of balancing it on the case mouth.
• Uses a free-floating, self-centering seating stem that holds the bullet in alignment with the case for concentric seating results.
• Threads into any press with the standard 7/8 inch-14 die thread.
• Backed by RCBS’s Limited Lifetime Warranty and made in the USA.
