The RCBS Legacy 3-Die Roll Crimp Set for .40-70 Sharps Straight (part no. 19204) is built for the black-powder-cartridge-rifle crowd running original or reproduction Sharps rifles chambered in this round. RCBS’s Legacy series keeps older, lower-volume chamberings like this one in dedicated production rather than leaving reloaders without an option. The set covers sizing, expanding, and roll-crimp seating in three steel dies.

Key Specifications

• Steel Sizer Die resizes the fired case body back to spec and de-primes it in the same stroke.
• Expander Die opens the case mouth to the correct inside diameter and flares it so the cast or jacketed bullet seats straight.
• Seater Die seats the bullet to the correct overall length before the crimp is applied.
• Roll crimp applied by the seater die locks the bullet in place for reliable feeding and recoil resistance.
• Cases must be lubricated before sizing since these are steel, not carbide, dies.
• Part of RCBS’s Legacy series built specifically to support older black-powder-era cartridges still fired in original and reproduction rifles.
