I am getting back to loading on my 650 after a long hiatus and moving it from my old house to a new one. In setting it up, the case insert slide isn't pushing the case far enough into the shell plate so the sizing die doesn't line up when it comes down. This is not an issue with the camming pin. At full insertion, the camming pin isn't touching the pistol side of the slide cam. The inward motion of the case insert slides is being stopped by the case insert slide contacting the platform in the location on the picture. It causes the case insert slide to twist a little on part of the platform it sits on. It seems that the normal case insert adjustments aren't going to fix this problem and the needed adjustment is somewhere else. Any hints?
