Lee Factory Pistol Crimp Die .30 Luger$18.75
Availability: In Stock
The Lee Precision Factory Crimp Die for .50 BMG delivers a firm, consistent crimp that goes beyond what standard seating dies can achieve. Built for the specialized reloader who demands precision with one of the largest rifle cartridges, this die uses a collet mechanism to squeeze the case mouth into the bullet's crimp groove with authority. The result is a more uniform pressure curve, reduced velocity variation, and measurably better accuracy—even with bullets that lack a traditional crimp groove.
If you're working up loads for a .50 BMG rifle or machine gun platform, you already know that consistency matters at this scale. A firm crimp prevents bullet movement before pressure builds, which stabilizes your ballistic curve downrange. This die fits any reloading press that accepts standard 7/8"-14 threaded dies, making it a straightforward addition to your .50 BMG setup once you have the correct shellholder on hand.
Lee's Factory Crimp Die is purpose-built for shooters serious about precision rifle reloading. Whether you're preparing match ammunition or working to maximize accuracy from a specialty big-bore rifle, this die addresses one of the most overlooked variables in the handloading process: the quality and uniformity of the crimp itself.

Yes. Testing shows that the Lee Factory Crimp Die crimps bullets firmly in place regardless of whether they have a dedicated crimp groove, and accuracy improves even in those cases.
A firm crimp prevents the bullet from moving forward as pressure builds in the chamber, which ensures pressure reaches a consistent peak level. This more uniform pressure curve results in reduced velocity variation and tighter group accuracy.
