The Lee Factory Crimp Die, .375 Ruger (Lee part no. 90609) is a factory crimp die built for Lee‘s die lineup, sized specifically for .375 Ruger. Rather than relying on a cannelure to hold the crimp, it squeezes the case mouth firmly enough that the bullet stays put even on projectiles with no crimp groove cut into them at all. It uses a standard 7/8-14 thread, so it drops into any single-stage or turret press without an adapter. A firmer crimp raises the pressure needed to start the bullet moving, which gives a more uniform pressure curve and less shot-to-shot velocity spread than a light or inconsistent crimp. It’s meant to run as the last station in your die sequence, after sizing and seating.

Frequently Asked Questions

Does this crimp die work on bullets without a cannelure for .375 Ruger? Yes — the crimp comes from squeezing the case mouth itself, so it holds bullets with no crimp groove just as well as ones with one.

Why does a firmer crimp matter? It raises the pressure needed to start the bullet moving, which produces a more uniform pressure curve and tighter velocity consistency shot to shot.

Is this a full sizing-and-seating die set? No — this is the crimp station only, meant to run last after your .375 Ruger sizing and seating dies.
