Description
Lee 338 Winchester Magnum/338-06 A SQUARE Factory Crimp Die crimps the bullet in place more firmly than any other tool. Tests demonstrate that even bullets which have no crimp groove will shoot more accurately. A firm crimp improves accuracy because pressure must build to a higher level before the bullet begins to move. This higher start pressure insures a more uniform pressure curve and less velocity variation.
Specifications and Features:
- Crimps bullet in place more firmly than any other tool
- Impossible to buckle case
- Trim length is not critical
- Bullets without cannelure shoot more accurately with the factory crimp die
