Lee Precision, Inc. .416 Rigby Rifle Factory Crimp Die

The Lee .416 Rigby factory crimp Die (custom over-run) secures the bullet more firmly than any other tool. Tests indicate that even bullets lacking a crimp groove achieve greater accuracy. A firm crimp enhances accuracy by requiring pressure to reach a higher level before the bullet initiates movement. This increased starting pressure ensures a more consistent pressure curve and reduces velocity variation. .416 Rigby (1-1/4-12 thread) factory crimp die, designed exclusively for use with the classic cast press Incorporates a collet mechanism that compresses the case mouth into the crimping groove to ensure a secure hold Compatible with all reloading presses featuring a 7/8-14 thread
