The Lee Precision 90076 Factory Crimp Die delivers consistent bullet seating depth and proper case mouth crimping for .357 SIG cartridges. This precision-engineered die ensures reliable feeding and optimal accuracy by applying uniform crimp tension across all reloaded rounds.
What Makes This Different
Unlike standard taper crimp dies that only resize the case mouth, the Lee Factory Crimp Die uses a collet system that applies radial pressure around the entire case mouth circumference. This dual-action design both sizes the cartridge to factory specifications and applies the precise crimp needed for semi-automatic pistol reliability. The result is ammunition that chambers smoothly and maintains consistent bullet retention under recoil.Key Features
