The Lee Precision 90854 Factory Crimp Die delivers consistent bullet retention and improved accuracy for 44-40 Winchester cartridges. This specialized reloading die applies factory-style crimping that maintains proper case mouth tension while preventing bullet setback during feeding and handling.
What Makes This Different
Unlike standard roll crimp dies that can buckle case walls, the Factory Crimp Die uses a collet system that applies uniform radial pressure around the entire case mouth. This design works with both cannelured and non-cannelured bullets, providing consistent crimp depth regardless of bullet variations. The die eliminates the guesswork associated with traditional crimping methods by automatically adjusting to case length variations.Key Features
