The RCBS 3-Die Roll Crimp Set for .500 S&W Magnum/Special (part no. 23808) is RCBS’s Group B pistol-cartridge answer for one of the hardest-hitting production revolver rounds on the market. The set includes three steel dies covering sizing, expanding, and roll-crimp seating, letting reloaders load both .500 S&W Magnum and .500 S&W Special cases on the same tooling. It’s built for revolver shooters who load heavy-bullet .500 ammunition and want a positive crimp for reliable ignition under recoil.

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.

Frequently Asked Questions

Does this set load both .500 S&W Magnum and Special? Yes, both cartridges share the same case diameter and this set is cataloged for both.

Why does a heavy revolver round need a roll crimp? A firm roll crimp keeps the bullet from jumping the crimp under recoil, which is especially important in a hard-kicking cartridge like .500 S&W.
