The RCBS 3-Die Roll Crimp Set (model R19304) is a specialized, mechanical reloading toolset from the RCBS Legacy Series. Designed specifically for historical and vintage cartridge reloaders, this set provides the necessary tooling to process, resize, and roll-crimp .45-90 Winchester and .45-90 2.4" Sharps Straight metallic black powder cartridges. Operating as a purely mechanical handloading system, this three-die configuration is built to handle the unique processing steps required for straight-walled rifle brass.

Key Features

• Three-Die Configuration: Includes a steel Sizer Die to resize the case body and deprime spent primers, an Expander Die to expand the case neck and apply a mouth flare, and a Seater Die to seat the bullet and apply a heavy roll crimp.
• Roll Crimp Finish: The seating die delivers a secure roll crimp, which is essential for managing recoil and ensuring reliable feeding in traditional single-shot rifles and tubular magazine lever guns.
• Standard Thread Interface: Built with the industry-standard 7/8"-14 thread pattern, ensuring compatibility with the vast majority of single-stage and turret reloading presses.
• Steel Construction: Machined from hardened steel for high precision and long-term durability when properly maintained.

Who is the Rcbs 45-90 3 Die Set for?

• Cowboy Action Shooting enthusiasts — require the Rcbs 45-90 3 Die Set to prepare ammunition for vintage-style competition, relying on the 7/8"-14 thread pattern to securely mount the tooling into standard single-stage presses for processing 2.4" black powder cartridge cases.
• Historical rifle shooters — operating reproduction or vintage single-shot and lever-action firearms chambered in .45-90 Winchester require this legacy rifle reloading die set, which weighs between 1.36 and 2.01 lbs, to apply a heavy roll crimp that prevents bullet movement under recoil.

Less suitable for: reloaders working with shorter .45-70 Government cartridges or longer .45-100 and .45-120 cases, as the physical dimensions of these dies are optimized strictly for the 2.4" case length; these shooters require cartridge-specific reloading dies sized for their exact case dimensions. It is also less suitable for high-volume progressive reloading operations requiring lube-free processing, which would otherwise use carbide sizing dies.
