To fix the case feed issue on the LnL I replaced the support bracket for the case feeder, that is the square red tube. The cast bracket for the pivot mounts to this tube, and the screw for mounting it applies enough pressure to distort the tube which throws it out of alignment. The other cause of the problem is having a case hang up in the mechanism so that it falls from the pivot all the way to the plate in front of the v-block, this is usually an adjustment issue caused by the threaded rod that controls the amount of pivot becoming loose.
Oh, and Hornady did send me the free replacement parts that I needed. Not sure how they thought a new lg primer pickup tube is supposed to help, but they included one and I don’t mind having another since it fits my RCBS bench primer, a wonderful tool!
