Lee Precision Factory Crimp Die 444 Marlin

The Lee Factory Crimp Die is a single-die reloading tool built specifically for the 444 Marlin straight-walled rifle case. Its job is simple and important: it puts a factory-style crimp on the case mouth so every loaded round holds the bullet firmly in place for consistent ignition and reliable feeding.

This Crimp Die is machined from steel and features the standard 7/8x14 thread used on most large-rifle reloading presses. Lee designed the Factory Crimp Die to replicate the crimp found on factory-loaded 444 Marlin ammunition, applying a tighter, more uniform crimp than other reloading tools. It is the finishing touch in any 444 Marlin reloading setup, pairing with a full-length sizing die, powder-through expanding die, and a bullet seating die.

From heavy hunting bullets for big game to range ammo, this Factory Crimp Die from Lee Precision helps reloaders produce consistent, factory-grade crimps on every round.
