Lee Taper Crimp Die, 45 Colt/454 Casull

The Lee Taper Crimp Die, 45 Colt/454 Casull (Lee part no. 90786) is a hardened-steel taper crimp die from Lee built to apply a straight taper crimp to jacketed pistol bullets instead of a roll crimp. It is set up for 45 Colt and 454 Casull, and similar cases sharing that same crimp diameter. Taper crimping is the correct crimp style for cartridges headspacing off the case mouth, and it requires a jacketed bullet with a proper crimp groove or cannelure to work correctly.

Frequently Asked Questions

What is a taper crimp and why use one? A taper crimp closes the case mouth straight against the bullet instead of rolling it into a groove, which is the correct crimp for cartridges that headspace off the case mouth rather than the rim.

Does this work with cast lead bullets? It is designed for jacketed bullets with a proper crimp groove or cannelure; cast bullets without one may not taper crimp cleanly.
