The RCBS Carbide 3-Die Roll Crimp Set (Model: R19112) is a precision-engineered, manually operated tool set designed specifically for reloading .45 Colt (.45 Long Colt) brass ammunition. Built for straight-walled revolver cartridges, this mechanical die set features a diamond-lapped, mirror-smooth tungsten-carbide sizing ring integrated directly into the sizing die. This advanced construction allows handloaders to resize spent brass cases back to factory specifications without applying case lubrication, eliminating the risk of stuck cases and reducing preparation time on the reloading bench.

Key Features

• Tungsten-Carbide Sizing Ring: The resizing die features a highly polished tungsten-carbide ring that resizes brass dry and includes a built-in decapping unit to remove spent primers in a single stroke.
• Expander Die: Properly expands the interior case mouth to receive new bullets, imparting a precise flare to prevent case neck crushing during bullet seating.
• Roll Crimp Seating Die: Seats the bullet to the correct depth and applies a secure physical roll crimp into the bullet cannelure, which is necessary to prevent bullets from slipping forward under heavy revolver recoil.
• Industry-Standard Threads: Features a standard 7/8"-14 thread pitch to ensure seamless compatibility with most single-stage and progressive reloading presses.
• Protective Storage: Shipped in a durable, grey plastic storage box to organize and protect the dies when not in use.
