RCBS .300 RUM Full Length Die Set for Reloading Bottleneck Cartridges

300 REM ULTRA MAG GP-A

The RCBS .300 Remington Ultra Magnum Full Length Die Set (Part Number 17601) is designed for precise and reliable reloading of .300 RUM cartridges. This two-die set includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with a built-in bullet seater plug, streamlining your reloading process. The Full-Length Sizer Die ensures your cases meet SAAMI minimum cartridge dimensions by resizing the outside of the case, removing the primer, and expanding the neck to accept the bullet. It features a venting system to prevent trapped air and excessive lubricant buildup, which helps maintain case integrity and prolong die life. Headspace is carefully controlled to minimize changes to case length during full-length resizing, ensuring consistent chamber fit and reliable performance. The Seater Die is equipped with a built-in roll crimper, allowing you to seat and secure bullets in one step, enhancing efficiency and precision during reloading. Crafted for durability and consistent results, this set is an essential addition for reloaders working with large magnum cartridges. Its compact dimensions make it easy to handle and store, while its specialized design guarantees a high-quality reload every time. Whether you're preparing for hunting, target shooting, or competition, this die set helps you achieve accurate and consistent ammunition with minimal effort.
