The Lee Precision .277 SIG FURY Factory Crimp Die incorporates a collet to apply a rifle type crimp to the case. Bullets do not need a crimp groove, as the collet is so powerful it will form one. This specialized reloading die makes .277 SIG FURY ammunition reloading more efficient, even when working with difficult-to-crimp cartridges.
A firm crimp improves accuracy because pressure must build to a higher level before the bullet begins to move, and this higher start pressure insures a more uniform pressure curve and less velocity variation. The Lee 277 Sig Fury Factory Crimp Die crimps the bullet in place more firmly than any other tool, and tests demonstrate that even bullets which have no crimp groove will shoot more accurately. The die features a standard thread of 7/8-14.
This die is not carbide, and it is manufactured to Lee Precision’s exacting standards. The model 91990 represents limited production for the newer .277 SIG FURY cartridge, making it an essential tool for reloaders working with this advanced rifle ammunition.
