Description

The Redding 31155 is engineered for shooters who require absolute consistency in their crimp. In semi-automatic platforms like the AR-10, M1A, or SCAR-17, a taper crimp is essential to prevent “bullet setback” during the violent cycling of the action. Unlike a roll crimp, which can buckle the case shoulder, this Taper Crimp die applies inward pressure to the case mouth, securing the bullet firmly while maintaining the cartridge’s headspace integrity.

The integrated Micrometer allows the user to adjust the amount of “squeeze” with surgical precision. This is particularly useful when dealing with varying brass wall thicknesses across different brands (e.g., thick military Lake City brass vs. thinner commercial Winchester brass). Once you find the perfect setting for a specific load, you can record the micrometer value and return to it instantly.

Key Features
Micrometer Adjustment: Dial in your crimp in .001″ increments for repeatable accuracy.

Specialized Taper: Designed to remove the “flare” from the case mouth and provide a secure grip on non-cannelured match bullets.

Standalone Operation: Allows you to seat the bullet to depth in one step and apply the crimp in a separate, final step—the preferred method for reducing bullet runout.

Polished Interiors: Hand-polished crimp surfaces prevent marring or “shaving” of the brass.
