Redding Titanium Carbide Taper Crimp Die Features The Redding Taper Crimp Die Set is designed for cartridges used in handguns with headspace on the case mouth and where more conventional roll crimping is not preferred. For people who do reloading and want a taper crimp and more uniformity the set is also available for certain revolver cartridges. With a taper crimp the process is gentler and tighter which in turn holds the bullet more firmly in place. However the overall length of the cartridge is not compromised. Constructed from steel this set is made to last. Redding Titanium Carbide Taper Crimp Die Specifications Brand: Redding Reloading Caliber: 41 Mag Reloading Die Type: Crimp
