The RCBS Safari Die 3-Die Roll Crimp Set, .500 Nitro (brand part no. 24804) is RCBS’s three-die roll-crimp system for straight-wall dangerous-game cartridges, the class of ammunition built for African safari calibers where a bullet has to stay put under heavy recoil. The steel sizer die sizes the case and de-primes it in one step (cases must be lubricated first). The expander die opens the case mouth to the proper diameter and imparts the flare needed for smooth bullet feeding. The seater die then seats the bullet and applies a roll crimp, the crimp style dangerous-game loads rely on to keep bullets from telescoping into the case under recoil. It’s a proven, purpose-built setup for .500 Nitro Express reloaders loading for heavy, fast-repeating shots.
