RCBS
The RCBS Sharps Straight 3-Die Roll Crimp Set is purpose-built for reloaders working with .50-70 Government and other straight-wall cartridges. This legacy caliber demands quality tooling that respects its history and ballistics, and RCBS delivers a three-die system that handles every stage of the loading sequence—sizing, priming, expansion, and seating—with the precision serious handloaders expect.
Straight-wall cartridges like the .50-70 Gov't require a different approach than bottleneck rounds, and this set reflects that reality. The sizer die shrinks fired cases back to spec and removes spent primers in one stroke. The expander die then opens the case mouth and creates the bell necessary for reliable bullet seating and feeding. Finally, the seater die seats your bullet while simultaneously applying a roll crimp to lock everything together. All three dies are machined steel, made in the USA, and designed to work together as a system. Note that this caliber and die set require case lube during sizing—standard practice for straight-wall loading.
Whether you're loading for a Sharps rifle, a custom single-shot, or another .50-70 Gov't platform, this three-die set gives you the dedicated tooling these classic cartridges deserve. RCBS has been the standard in American reloading for generations, and their legacy straight-wall dies prove why.
| Caliber | .50-70 Government |
| Die Type | Straight-wall, 3-die set with roll crimp |
| Material | Steel |
| Manufacturer | RCBS |
| Country of Origin | USA |

Yes. Cases must be lubricated during the sizing process to prevent sticking and ensure smooth operation of the sizer die.
The set includes a sizer die (which also de-primes), an expander die (which creates the case mouth bell), and a seater die with integrated roll crimp function.
RCBS dies use standard press tooling. Verify your press accepts standard die threads and confirm press compatibility with your specific reloading setup before ordering.
