Taper Crimp Die Explanation

The Pistol Bullet Seating Dies currently produced have a Taper crimp "built" into the die. So the Taper Crimp Die performs the same function as the Bullet Seating Dies included in any Pistol Die Sets manufactured after 1986. Unfortunately there are still some other die manufacturers that have not mastered the art of case crimping and this die will fix any issues caused by those dies as well as our Lee Bullet Seating Dies made prior to 1986.
