The Lee 357 Sig Factory Crimp Die is designed specifically for the .357 Sig bottleneck cartridge. This single-die reloading tool crimps the bullet firmly in place, and a firm crimp improves accuracy by requiring pressure to build to a higher level before the bullet begins to move.
Specifications: The die measures 1.60 X 1.70 X 4.70 inches (Height: 1.6000″, Width: 1.7000″, Length: 4.7000″). This Factory Crimp Only die is non-carbide and comes as a single die in the set, calibrated for .357 Sig cartridges.
