Lee Precision 6.5x55 Swedish Mauser Factory Crimp Die

Lee Precision Factory Crimp Die 6.5x55 Swedish Mauser

The Lee Precision Factory Crimp Die in 6.5x55 Swedish Mauser is a die dedicated solely to crimping, designed to be mounted as a separate station after the seating die. Separating bullet seating from crimping allows both operations to be adjusted independently and is the standard choice for those reloading rifle cartridges for hunting and target shooting, where the round must withstand recoil, magazine feeding, and handling.

The die works with a collet system: steel segments close radially on the case neck and secure the bullet with pressure distributed across the entire circumference. Since the crimp is created by the closing of the collet rather than contact between the case mouth and the die mouth, the result remains consistent even when cases are not of equal length, unlike the roll crimp produced by a seating die. Lee states that a firm crimp increases starting pressure, creates a more uniform pressure curve, and reduces velocity spread, noting that the system also works with bullets lacking a cannelure.

Main features

• Collet-style crimp-only die for rifle cartridges
• Caliber: 6.5x55 Swedish Mauser
• Uniform crimp around the entire circumference of the neck
• Consistent results even with cases of uneven length
• Effective even with bullets without a cannelure or crimp groove
• 7/8"-14 threaded body, standard for reloading presses
• Crimp intensity adjustable by screwing the die body

Recommended use

It screws into any reloading press with standard 7/8"-14 threading, including Lee single-stage, turret, and progressive presses. It should be used as a separate station after adjusting the seating die so that it does not crimp: the bullet is first seated to the desired depth and then crimped in a dedicated pass.

Package contents

The package contains the Factory Crimp Die complete with a Spline Drive lock ring and operating instructions. It does not include a shell holder, resizing die, or seating die, which are part of Lee die sets or must be purchased separately.
