[QUOTE="Centre Punch, post: 126256, member: 3048"] Longdraw, Are you using the Lee Collet die? My buddy had the same thing happen when he used the collet die but not when he used other dies. It turned out that the neck was not being adequately sized to hold the bullet tight enough in order to build up enough pressure to completely obturate the chamber. Polishing a couple of thou off the mandrel cured the problem most of the time, my buddy has since changed dies. Ian. [/QUOTE]
