Lee Factory Rifle Crimp Die .45-70 Gov't

The Lee Factory Rifle Crimp Die for .45-70 Government (Model 90856) is a precision reloading tool designed to apply factory-spec crimps while simultaneously post-sizing rifle cartridges. Unlike standard crimp dies, this tool guarantees consistent chamber fit across every completed round by combining sizing and crimping in a single operation, ensuring ammunition performs exactly as it would coming straight from the factory line.

The die features a carbide sizer that handles the full range of .45-70 Government ammo, from jacketed bullets to lead projectiles regardless of cannelure presence. Adjustment is straightforward—a single screw controls crimp depth, allowing the operator to dial in the exact amount needed for individual cartridge specifications. The robust construction delivers sufficient crimping force even on non-cannelured bullets, eliminating the risk of bullet setback during chambering or recoil cycling.

This tool is essential for handloaders working with .45-70 Government rifle ammunition in bolt-action, lever-action, or semi-automatic platforms. Reloaders prioritizing ammunition reliability and consistency—whether for hunting, long-range target work, or precision rifle applications—depend on factory-spec crimping to prevent case separation and maintain proper bullet engagement. The Lee Factory Rifle Crimp Die integrates seamlessly into standard progressive or single-stage press setups and represents a professional-grade solution for serious .45-70 Government ammunition production.
