RCBS 17701 Full-Length 2-Die Set .338 Rem Ultra Mag - Group A

The RCBS 17701 is a Full-Length 2-Die Set purpose-built for reloading the .338 Remington Ultra Magnum bottleneck cartridge. Part of RCBS's workhorse Group A line, this set delivers the dependable two-die workflow that has made RCBS a long-standing standard in rifle reloading.

The set includes two steel dies: a Full-Length Sizing Die with an integrated Expander-Decapping Unit that resizes the fired case and removes the spent primer in a single pass, and a Seater Die with a dedicated Bullet Seater Plug that seats the bullet to your chosen overall length. Together they cover every step needed to turn fired .338 RUM brass back into loaded ammunition on any standard reloading press.

Designed for bottleneck rifle cases, the full-length sizer brings the case body and shoulder back to SAAMI spec so the round will chamber reliably in factory-spec .338 Remington Ultra Magnum rifles. The seater die accepts RCBS's standard seating stem system for fine-tuning bullet jump and seating depth. This is a direct, no-frills solution for hunters and long-range shooters who want to reload their own .338 RUM ammunition with the consistency and confidence RCBS tooling is known for.
