Yeah Zeke, I usually tap it a bit after each adjustment. I hope I owe Leopold a big apoligy and find something else wrong that caused my problem but I don' t know what in the world it would be, I just did' nt have time to mount it again during our season, I will try to get it put on over the next few days and I will try and be sure to post whatever the outcome, I know my gun and I know how it groups, I hope its fixed without having to send it in again, but right now I have my doubts if they did' nt do anything to it, they said they did' nt except take it apart and check it.
