Note to those who have had trouble with a Dillon 550b and CCI (or other primers). There is a small Allen-head screw with a lock-nut that controls how the primer tube and the primer cup line-up, fore and aft. When a primer does not drop into the primer cup,or if the primer drops into the cup sideways, a very subtle adjustment of that screw almost always eliminates the problem. Sometimes one brand of primer feeds perfectly, where as another will have an occasional miss-feed and will require a slight screw adjustment. It is just the nature of the priming system.
