I tried all of the above without success. The problem I found was that my powder funnel was set to deep. It was allowing the bullet to drop into the case too far and a second bullet to follow. When the shell plate was lowered and the three bullet catch bearings came out of their recessed groove, two bullets had passed. By shortening the depth that the first bullet was allowed to enter the case, the second bullet was trapped behind the three bearings as the shell plate was lowered. Now it works perfectly!!!!
