I have the Lee LoadMaster. I had trouble with the case feeder at first. On the loadMaster there is a long square rod that a slider rides on that operates the case slider via a "Z" bar. putting a little STP on that rod fix my problems. on the loadmaster that rod sticks out at a 45 degree angle from the press. Sorry but I just don't recall how it works on the pro 1000. do not put stp on the place where the case rides. I pesume you have double checked your indexing.
