Redding Micro-Adjusting Taper Crimp Dies

New for 2013, Redding has introduced a series of innovative Micro-Adjusting Taper Crimp Dies for many of the popular straight wall cartridges used in competitive shooting today.  These are top adjusting with no need to remove the die and reposition the lock ring like traditional taper crimp dies when setting a proper crimp.

High volume, progressive, reloaders have struggled for years with the realities of case variation and the resulting difficulties in obtaining a uniform crimp.  Case length is not the only variable, as case wall thickness also impacts where the case intersects the die’s tapered crimping surface.

The process of traditional taper crimp die adjustment is generally both time consuming and imprecise due to the 1 in 14” thread pitch coupled with the need to reposition the lock ring after each adjustment.

The new Redding Micro-Adjusting Taper Crimp Dies use a knurled, micrometer type head situated on top of the die to provide approximately + or -0.100” of “on the fly” adjustment after initial set – up.  They use a truly innovative “Free Floating” internal sleeve of hardened steel to form the crimp.  This barrel is unique because it can accommodate one specific taper in each of its ends for two cartridge types having a closely related body diameter.  Example. with a simple removal and rotation of this taper crimp barrel, the die can be switched from a 38 Super family cartridge to a 9mm family cartridge.

The initial dies offered are available in 9mm/38 Super, 45 ACP /45Gap and 40 S&W / 10mm.  The die body thru holes are machined to very tight tolerances providing a close fitting lead into the die for a maximum retention of finished round concentricity. 

Down time and loss of production due to adjustment of the crimp are virtually eliminated, dramatically increasing the rounds per hour rates of all progressive and turret style presses.
