The Lee Precision 90780 Taper Crimp Die delivers consistent bullet seating depth and proper case mouth tension across four popular pistol calibers. This precision-machined steel die eliminates case mouth flare while maintaining optimal bullet retention for reliable feeding and accuracy.
What Makes This Different
Unlike roll crimp dies that can deform bullet profiles, this taper crimp design preserves bullet shape while creating uniform case tension. The hardened steel construction maintains dimensional stability through thousands of reloading cycles. Multi-caliber compatibility reduces die inventory requirements for reloaders working with multiple cartridge types in the same bullet diameter range.
Key Features
- Compatible with 9mm Luger, 38 ACP, 38 Super, and 380 ACP cartridges
- Taper crimp design preserves bullet profile and jacket integrity
- Hardened steel construction with precision-ground interior surfaces
- Standard 7/8-14 threading fits most single-stage and progressive presses
- Knurled lock ring provides secure positioning and quick adjustments
- Factory-set crimp diameter eliminates guesswork during setup
- Removes case mouth flare while maintaining proper bullet tension
Consistent crimping pressure ensures reliable chambering in semi-automatic pistols while preventing bullet setback during feeding cycles. The die works effectively with both jacketed and lead bullets, maintaining proper case-to-bullet interface across different projectile types. Shooters report improved accuracy and reduced feeding issues when switching from factory ammunition to properly crimped handloads.
