Redding Micrometer Adjustable Crimping Die, 38 Special/357 Magnum

Top adjusting for progressive presses with tight space constraints

Redding’s new Micrometer Adjustable Crimping Dies are top adjusting to simplify making precise adjustments because any variation in case length and wall thickness both adversely affect proper adjustment.

Traditional Taper Crimp Die adjustment is both time consuming and imprecise due to the coarse 7/8 - 14 pitch die threads and the need to re-position the lock ring, this is especially important to users of progressive reloading presses with tight space constraints.

The new Micrometer Adjustable Crimping Dies have a knurled micrometer barrel situated on the top of the die for easy access and provides approximately ± .100” of “on-the-fly” adjustment in .001” increments.

Versatility is enhanced on handgun dies by being able to reverse the internal crimping sleeve to accommodate two different cartridges having closely related body diameters. An example is the 38 Super and the 9mm family of cartridges. Rifle cartridges are non-reversible.
