RCBS Carbide Taper Crimp 3 Die Set .40 S&W/10 Auto

• Carbide sizing die: The tungsten carbide sizing ring sizes straight-wall pistol brass without routine case lubrication, which speeds up loading sessions and keeps case handling cleaner.
• Taper crimp seating die: The seating die applies a taper crimp suited to .40 S&W and 10mm Auto ammunition, helping reduce bullet setback and supporting smoother feeding in self-loading pistols.
• Three-die layout: Separate sizing, expanding and seating/crimping operations give better control over each step of the loading process, which is useful when tuning loads for consistency.
• Standard 7/8"-14 thread: The dies fit common reloading presses, making the set easy to integrate into an existing bench without special adapters.
• Made in USA: Production in Oroville, California supports consistent manufacturing standards for reloaders who want durable tools for regular pistol cartridge loading.

About the Series Series

RCBS carbide taper crimp die sets are built for reloaders working with straight-wall pistol cartridges that benefit from a dedicated sizing die, a separate expander die and a seating die that also applies a taper crimp. Within the RCBS lineup, these sets sit as a practical choice for handgun loading where reliable chambering and repeatable case preparation matter more than all-in-one compromise tools. They are intended for routine loading of popular autoloading pistol calibers used in range shooting, training and general-purpose handgun ammunition assembly.

A defining feature of the series is the carbide sizing die, which reduces the need for case lube during normal sizing of pistol brass and helps speed up repetitive bench work. RCBS also uses a stepped expander die to open the case mouth in a controlled way for easier bullet seating, while the taper-crimp seating die is designed for cartridges that headspace on the case mouth. That layout reflects a straightforward mechanical design philosophy: durable dies, conventional press compatibility and separate operations that let the handloader adjust sizing, expansion and seating with more precision.

About the RCBS Carbide Taper Crimp 3 Die Set .40 S&W/10 Auto

The RCBS Carbide Taper Crimp 3 Die Set .40 S&W/10 Auto is configured for reloaders who work with .40 S&W Auto and 10mm Auto, two cartridges that demand consistent case preparation for dependable feeding in semi-automatic pistols. Its carbide sizing die handles decapping and full-length sizing in one step, restoring fired brass to usable dimensions while avoiding the routine lubrication normally associated with steel sizing dies. For anyone loading in volume, that means less interruption between batches and a cleaner workflow at the press.

The separate expander stage is useful with handgun brass because it prepares the case mouth for bullet seating without excessive flare, helping bullets start straighter and reducing the chance of shaving plated or jacketed projectiles. The seating die then combines bullet seating with a taper crimp, which is the correct style for these autoloading pistol cartridges. In practical terms, that crimp helps control bullet retention and supports more reliable feeding from magazine to chamber.

Because the set uses a standard 7/8"-14 thread, it fits the common press format used on many single-stage and turret setups. The straight-wall case design, standard adjustment system and RCBS die construction make it a sensible choice for reloaders who want a conventional, durable die set for regular handgun ammunition production rather than a specialized competition-only tool.

About RCBS

RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. The company name came from “Rock Chuck Bullet Swage,” the original bullet-swaging die that started the business. RCBS focuses on ammunition handloading and reloading equipment for rifle and pistol cartridges, with product lines that include presses, dies, shell holders, powder measures and priming tools. It also offers single-stage, turret and progressive press systems, which has helped make the brand a long-standing reference point for reloaders building complete bench setups around one system. RCBS manufactures reloading tools in Oroville, California, and became a brand of Hodgdon Powder Company after its sale by Revelyst in 2024.
