The Lyman Premium Carbide 4 Die Set .45 ACP (SKU: LY-PC45) is a high-grade reloading system engineered for precision, longevity, and high-volume ammunition production. Specifically designed for the .45 ACP cartridge (and also compatible with .45 Winchester Magnum), this premium four-die set is built to meet the rigorous demands of Australian handloaders and competitive pistol shooters. By utilizing a dedicated four-die configuration, this set separates the bullet seating and taper crimping processes. This separation is highly beneficial for semi-automatic cartridges like the .45 ACP, which headspace on the case mouth, ensuring consistent chambering, reduced bullet shaving, and improved overall accuracy.

Key Features:

• Tungsten Carbide Sizing Die: The sizing die features an ultra-hard tungsten carbide insert that eliminates the need for case sizing lubricant, streamlining your reloading workflow and keeping your brass clean.
• Two-Step Neck Expander "M" Die: Lyman's proprietary "M" die uses a two-step process to expand the case neck to just under bullet diameter and then flare the mouth slightly. This ensures bullets sit perfectly straight and centered before seating, preventing shaved jackets or lead.
• Dedicated Taper Crimp Die: By separating the seating and crimping steps, this set applies a precise taper crimp to ensure reliable feeding and proper headspacing in semi-automatic handguns.
• Universal Compatibility: Built with standard 7/8"-14 threads, these dies are fully compatible with virtually all standard single-stage, turret, and progressive reloading presses.
• Durable Storage: Includes a heavy-duty plastic storage case to protect your investment and keep your reloading bench organized.
