Lee Precision 90786 Taper Crimp Die 45 Colt/454 Casull
$10.16
The Lee Precision 90786 Taper Crimp Die for 45 Colt and 454 Casull is a specialized reloading die built to solve crimp inconsistencies that can arise from cartridge design or previous die wear. If you're handloading these magnum revolver rounds and noticing uneven or unreliable crimps—especially when stepping up to hotter loads—this taper crimp die gives you direct control over case mouth engagement. It's made from hardened steel for the durability expected from a lifetime reloading tool.
Taper crimp dies work differently from standard crimping stages. Instead of forming a roll crimp around the case mouth, they apply a slight inward taper that grips the bullet securely without deforming it. For 45 Colt and 454 Casull handloaders, this approach is particularly useful when you're loading heavier bullets or working with brass that's seen multiple reloads. The controlled crimp also helps maintain consistent chambering and extraction across revolver cylinders.
Keep in mind that if you're already using Lee dies manufactured after 1986, the crimp geometry in those dies has already been optimized for taper crimping—so you may not need this as a separate step. This die is most valuable as a dedicated solution when you're dealing with older equipment, mixed brass sources, or situations where your primary die isn't delivering the crimp consistency you need.

Frequently Asked Questions
Do I need this die if I'm already using Lee dies from after 1986?
Probably not. Lee dies manufactured after 1986 already have a modified crimp angle optimized for taper crimping. This die is most useful for older equipment or when you need dedicated crimp control with other die systems.
What's the difference between taper crimp and roll crimp?
A taper crimp applies a gentle inward angle to the case mouth without rolling it. A roll crimp actually folds the case mouth around the bullet. For revolver rounds like 45 Colt and 454 Casull, taper crimps provide secure retention while preserving bullet integrity.
Will this work with mixed brass or reloaded brass?
Yes. This die is particularly helpful when working with brass that's been reloaded multiple times or sourced from different manufacturers, where crimp consistency may vary. It gives you a dedicated stage to dial in reliable crimp performance.
