RCBS 17801 Full-Length 2-Die Set Group A 7mm Remington Ultra Mag

The RCBS 17801 Full-Length 2-Die Set delivers precision reloading capabilities specifically engineered for 7mm Remington Ultra Magnum cartridges. This Group A die set combines RCBS's proven manufacturing standards with the exacting tolerances required for magnum rifle cartridge preparation. Reloaders gain consistent case preparation and bullet seating through hardened steel construction and precise machining.

What Makes This Different

This full-length die set features RCBS's Group A classification, indicating standard tapered expander systems optimized for conventional bullet designs. The sizing die provides complete case reformation from fired brass, while the bullet seating die offers micrometer-adjustable seating depth control. Each die incorporates RCBS's signature lock ring system that maintains consistent adjustments across reloading sessions, eliminating the setup variations common with basic die sets.

Key Features

• Full-length sizing die reforms entire case body and neck for reliable chambering
• Bullet seating die with built-in roll crimp for secure bullet retention
• Hardened steel construction with corrosion-resistant finish
• Standard 7/8-14 threading fits all major reloading presses
• Includes expander ball sized specifically for 7mm (.284") bullets

Field performance centers on the 7mm RUM's long-range capabilities, where consistent ammunition preparation directly impacts accuracy at extended distances. The full-length sizing ensures reliable extraction and feeding in hunting rifles, while precise bullet seating maintains the concentricity essential for sub-MOA accuracy. This die set handles the 7mm RUM's substantial case capacity and high-pressure loading requirements without dimensional drift.
