RCBS 300 RUM Dies Set with Shell Holder 38

Description

The RCBS 300 RUM reloading dies are professional-grade tools designed for handloaders seeking maximum accuracy and consistency. This two-die set is specifically engineered for the 300 RUM cartridge and includes everything needed to safely resize cases and seat bullets with precision.

Key Specifications

This RCBS 300 RUM dies set consists of a Full-Length Sizer Die with an integrated Expander-Decapping Unit and a Seater Die featuring a built-in Bullet Seater Plug. The dies are compatible with Shell Holder 38, ensuring secure case holding during the reloading process. The full-length sizer die brings cases to SAAMI minimum cartridge dimensions for optimal chamber fit and performance.

Performance & Ballistics

The Full-Length Sizer Die in this RCBS 300 RUM dies set sizes the outside of the case while de-priming and expanding the neck to accept bullets. Engineered vents prevent case damage caused by trapped air and excessive lubricant buildup. Headspace is held to minimum tolerances to avoid changing case body length during full-length sizing, preserving case integrity across multiple reloading cycles. The included Seater Die features a built-in roll crimper that secures the bullet at the same time it’s seated, creating uniform rounds for consistent ballistic performance.

Whether you’re developing custom loads for hunting, target shooting, or long-range precision competitions, this die set provides the accuracy and repeatability demanded by serious shooters. The 300 RUM cartridge is renowned for its power and long-range capabilities, making properly sized ammunition critical for peak performance.
