Lee Precision Factory Crimp Die 45-70 Government / 450 Marlin

The Lee Precision Factory Crimp Die is a single-die reloading tool designed for the 45-70 Government cartridge, and it is also compatible with 450 Marlin cases. Using a collet design, this die applies a tight, factory-style rifle crimp that seats the bullet firmly into the case mouth. Cut from steel, the Lee 90856 Factory Crimp Die is sold as a single die that adds a final crimping step to your reloading sequence.

A crimp die completes the reloading process by applying a uniform crimp to the case mouth after the bullet has been seated - a critical finishing step with heavy-recoiling, big-bore 45-70 Government and 450 Marlin loads. The Lee Factory Crimp Die grips the bullet securely so it stays in place under ignition pressure, and the collet will crimp even bullets that lack a dedicated crimp groove. It is a practical addition for any handloader working up 45-70 Government or 450 Marlin ammunition who wants a more positive bullet hold at the case mouth.
