The RCBS 3-Die Carbide Taper Crimp Set for .380 Auto (Model R20415) is a premium pistol reloading die set designed for high-precision handloading of .380 ACP ammunition. Built from polished and heat-treated proprietary die steel, this three-die assembly provides the essential steps needed to resize, expand, seat, and crimp straight-walled handgun cartridges. With its industry-standard thread interface, the set integrates seamlessly with most single-stage, turret, and progressive reloading presses used by Australian handloaders.

Key Features

• Carbide Sizing Ring: The sizing die features a high-durability carbide insert that resizes brass cases without requiring case lubrication, eliminating greasy residue and streamlining the reloading workflow.
• Taper Crimp Seating Die: Because the .380 Auto cartridge headspaces on the case mouth, this set applies a precise taper crimp rather than a roll crimp, gently removing the flare and securing the bullet for reliable semi-automatic feeding.
• Complete Three-Die Set: Includes a Carbide Sizing Die with an integrated decapping and depriming unit, an Expander Die to flare the case mouth, and a Bullet Seating Die with a built-in taper crimp function.
• Premium Construction: Crafted from hardened, polished steel to ensure longevity and minimize wear on both the dies and your cartridge brass.
