RCBS 18915 Carbine 3-Die Set Group B .45 ACP Reloading Dies

The RCBS 18915 Carbine 3-Die Set delivers precision reloading capabilities specifically engineered for .45 ACP ammunition. This Group B die set provides the essential tools for producing consistent, accurate rounds while extending brass life through proper resizing and bullet seating.

What Makes This Different

Unlike standard pistol die sets, this carbine configuration includes a taper crimp die that maintains proper case mouth tension without over-crimping. The hardened steel construction withstands thousands of reloading cycles while maintaining dimensional accuracy within 0.001 inches. RCBS precision manufacturing ensures consistent powder charges and bullet seating depth across every round produced.

Key Features

• Full-length sizing die removes case expansion and prepares brass for new primer
• Bullet seating die with built-in roll crimp for consistent bullet placement
• Taper crimp die eliminates case mouth flare while maintaining proper tension
• Hardened steel construction with precision-machined chambers
• Standard 7/8"-14 threads fit most single-stage and progressive presses
• Includes shell holder and detailed reloading instructions
• Group B classification optimized for .45 ACP case dimensions

This die set handles both jacketed and lead bullets effectively, producing ammunition suitable for target shooting, competition, and personal defense applications. The taper crimp design prevents bullet setback during feeding while maintaining consistent overall cartridge length. Temperature variations and extended storage periods have minimal impact on dimensional stability.
