anyone using a pro 2000 progressive press? im having trouble getting lrg. pistol primers to fall thru the drop tube when depriming.thanks howard

I have been using a Pro 2000 for 10 plus years and on occasion I will have the same problem with large primers hanging up at the mouth of the spent primer drop tube. I wish I had a fix for you, but I do not. All I do when this happens is clean the primer tube around the opening below the shell plate. I won't have a problem for awhile.
