RCBS Taper Crimp Seating Die .40 S&W/10mm

RCBS Taper Crimp Seating Die for .40 S&W and 10mm Auto

This specialized seating die from RCBS combines two essential reloading operations into a single, efficient step.

Key Features

• Dual Function Design: Seats the bullet while simultaneously applying a taper crimp
• Consistent Results: Built-in taper crimper ensures uniform crimp tension across all rounds
• Caliber Compatibility: Designed for .40 S&W and 10mm Auto cartridges
• Quality Construction: RCBS precision engineering for reliable performance

Why This Matters

Taper crimping is essential for semi-automatic pistol ammunition. Unlike revolver rounds that use roll crimps, pistol cartridges require a taper crimp to ensure proper feeding and extraction while maintaining bullet security. By combining seating and crimping in one die, you reduce setup time and improve consistency—each round receives identical treatment.

Application

This die is an essential component for handloaders who want to produce reliable, match-grade ammunition for competitive shooting, personal defense, or general practice with .40 S&W and 10mm Auto firearms.
