RCBS 3 Die Roll Crimp Set - Group C - Straight Walled Rifle Cartridges .45-70 Gov

The RCBS 3 Die Roll Crimp Set - Group C - Straight Walled Rifle Cartridges .45-70 Gov is an essential precision toolset for handloaders looking to maximize the performance of the classic .45-70 Government round. Designed for the high-pressure demands of straight-walled rifle cartridges, this set provides the necessary consistency for both lever-action hunters and long-range enthusiasts. By controlling every stage of the reloading process, users can ensure their ammunition meets specific tolerances that factory loads often overlook. This set is engineered to withstand high-volume reloading sessions while maintaining the tight specifications required for reliable cycling and accuracy.

This comprehensive kit includes a steel Sizer Die, an Expander Die, and a Seater Die to streamline the reloading workflow for straight-walled cases. The steel Sizer Die effectively brings the case back to factory dimensions while simultaneously de-priming the spent brass, though it requires proper lubrication to prevent stuck cases. The Expander Die is critical for this caliber, as it opens the case mouth to the exact diameter needed to accept a new projectile and provides a slight flare for smooth feeding. Finally, the Seater Die precisely seats the bullet to the desired depth and applies a roll crimp, which is vital for securing bullets against the recoil forces found in tubular magazines.

For those operating in the field or at the range, the RCBS 3 Die Roll Crimp Set - Group C - Straight Walled Rifle Cartridges .45-70 Gov offers the reliability needed for heavy-duty applications. The roll crimp feature is particularly important for .45-70 cartridges used in lever-action rifles, where magazine spring tension and recoil can otherwise cause dangerous bullet setback. This die set is compatible with most standard reloading presses using 7/8"-14 threads, making it a versatile addition to any professional reloading bench. Whether you are preparing rounds for a tactical lever-gun build or traditional big-game hunting, these dies deliver the professional-grade results expected from RCBS.
