RCBS
The RCBS 19108 Roll Crimp 3-Die Set for 45 Colt (LC) is purpose-built for handloaders who want reliable ammunition at the bench. This is a complete die set designed specifically for straight-wall cartridges like the 45 Colt, giving you everything you need to move cases through sizing, expansion, bullet seating, and crimping in a logical, efficient sequence. Whether you're loading for a classic revolver or modern lever gun, this set delivers the precision straight-wall reloading demands.
The three-die configuration starts with a steel Sizer Die that sizes your cases back to specification and removes the spent primer in one operation—just remember that 45 Colt cases need to be lubricated before sizing to protect both your brass and your dies. The Expander Die then opens the case mouth to the right diameter for bullet insertion and applies a controlled case mouth flare (or bell) that ensures smooth bullet feeding and helps seat bullets concentrically. The final step is handled by the Seater Die, which both seats your bullet to the correct depth and applies a roll crimp to lock the bullet in place for reliable cylinder performance.
RCBS has been the standard for reloading dies since 1956, and this Group B die set reflects that heritage—solid engineering without unnecessary complexity. If you're new to 45 Colt reloading or you're scaling up production, this set gives you a complete, matching system from a brand reloaders trust.
