Lee Factory Crimp Die crimps your bullets in place the same as factory ammo. A collet gently, but firmly squeezes the very end of the case into the crimping groove, exactly the same as factory ammo.
Gives a segmented straight crimp, and crimps more firmly than any other tool
It is impossible to buckle the case as with regular roll crimp dies
Necessary for hunting and combat. Ammunition will be more accurate and better able to withstand rough handling because the bullet is firmly crimped in place.
Tests demonstrate that even bullets with no cannelure will shoot more accurately if crimped in place with the Lee Factory Crimp Die. A firm crimp improves accuracy because pressure must build to a higher level before the bullet begins to move. This higher start pressure insures a more uniform pressure curve and less velocity variation. Even powder selection is less critical. Until now, handloaders seated the bullet to touch the rifling to achieve similar results. This is not always possible nor desirable.
The Lee Factory Crimp Die is included at no extra charge with Lee PaceSetter 3-Die set. It's just another added value that only Lee dies offer.

500 Linebaugh (too sort for large series die body and too large for standard series die body)
50 AE (case diameter is too large to fit in the 7/8-14 die and too short for large series as a collet type crimp die. It can not be made as a carbide crimp die because the carbide would end up being too thin to have the necessary strength. If you wish to separate the bullet seating and crimping steps then purchasing a separate seating die body is your best option.)
