Lee .300 ULTRA MAG /.300 H&H Factory Crimp Die

The Lee Factory Crimp Die crimps the bullet firmly in place. 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. It features a collet that squeezes the case mouth into the crimping groove for a firm hold. It is nearly impossible to buckle the case as with regular roll crimp dies. The Lee Factory Crimp Die is made of steel and comes packaged in a plastic storage box. NOTE: Lee Precision is phasing out the pictured storage boxes and replacing them with durable tube containers.
