RCBS 19108 Roll Crimp 3-Die Set Group B .45 Colt Reloading Dies

The RCBS 19108 Roll Crimp 3-Die Set delivers precision reloading for .45 Colt cartridges with consistent case preparation and bullet seating. This Group B die set produces ammunition that meets or exceeds factory specifications for both target shooting and hunting applications.

What Makes This Different

RCBS Group B dies feature hardened steel construction with precise tolerances that maintain consistency across thousands of reloading cycles. The roll crimp design creates a secure bullet hold while preserving case life, unlike taper crimp dies that can work-harden brass prematurely. Each die undergoes individual testing to ensure dimensional accuracy within 0.001 inches.

Key Features

• Three-die configuration includes full-length sizing die, bullet seating die, and roll crimp die
• Hardened steel construction with corrosion-resistant finish for extended service life
• Standard 7/8-14 threading fits all major reloading presses
• Roll crimp design maintains consistent bullet tension and case integrity

This die set handles the full range of .45 Colt loadings from light target rounds to heavy hunting loads. The sizing die returns fired cases to SAAMI specifications while the seating die positions bullets with repeatable precision. Roll crimping provides the secure bullet retention required for heavy recoil loads and revolver cylinder timing.
