Lee .30 M-1 Carbine/32-20 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 container.
