The RCBS 20904 Roll Crimp 3-Die Set Group C is purpose-built for reloading .45-70 Government, the classic straight-wall cartridge favored by hunters pursuing big game with lever-action rifles and single-shots. This three-die set gives you everything needed to process brass and assemble reliable ammunition for one of America's most storied hunting rounds. If you're working up loads for a Marlin, Winchester, or Sharps rifle, a dedicated .45-70 die set ensures proper sizing, bullet seating, and crimp — all critical for consistent performance in lever guns.
The set includes a full-length sizer die that resizes the case body and removes the spent primer, a separate expander die that opens the case mouth to accept your bullet and creates the slight flare needed for smooth feeding, and a seater die that seats the bullet and applies a roll crimp to lock it in place. The roll crimp is essential for .45-70 loads, especially in lever-action rifles where recoil and magazine handling demand a tight, secure crimp. Steel construction throughout ensures durability through thousands of reloading cycles. Remember that straight-wall cases like .45-70 brass require lubrication before sizing — don't skip that step.
Whether you're a .45-70 devotee fine-tuning loads for your favorite lever gun or a hunter looking to reload accurate, cost-effective ammo for dangerous game, this RCBS die set delivers the precision and reliability the caliber demands. It's a straightforward, proven approach to .45-70 ammunition assembly.
