Lee Factory Crimp, Lee 90076 Fac/crmp B/neck Die 357 Sig

Lee's factory crimp die crimps the bullet in place more firmly than any other tool.Tests demonstrate that even bullets which have no crimp groove will shoot more accurately.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.Type: Crimp DieCaliber: 357 SigDie Type: CrimpDie Series: CrimpIn Set: 1
