Lee Precision Taper Crimp Die 45 ACP / 45 Auto Rim / 45 Win Mag 90785

Lee Precision Taper Crimp Die 45 ACP / 45 Auto Rim / 45 Win Mag

The Lee Precision Taper Crimp Die for 45 ACP, 45 Auto Rim, 45 Schofield, 455 Webley Mark 2, and 45 Winchester Magnum is a single die that performs a taper crimp on the case mouth. This is the correct operation for all pistol cartridges that headspace on the case mouth: the taper crimp closes the flare left by the expander by progressively tightening the neck onto the bullet, without creating the ridge that a roll crimp would impose, which would compromise proper chambering.

Separating the crimping from the seating process is the most precise way to obtain uniform ammunition: the bullet is first seated to the desired depth, and only then is the case closed, preventing the bullet from being pushed while the neck is being tightened. Lee manufactures these dies from hardened steel and offers them as a solution to crimping problems caused by the inadequate design of other dies. The degree of crimp is adjusted by changing the height of the die in the press. Standard 7/8"-14 thread.

Recommended use

It screws into any press with 7/8"-14 threading and is used in the station following seating, after having deactivated the crimping function on the seating die. This is the recommended crimp for straight-walled cartridges that headspace on the case mouth; for revolver cartridges with a crimping groove, a roll crimp or the Factory Crimp Die is preferred instead.

One taper crimp die. Shell holder, resizing dies, and seating dies are not included.
