I agree with Waldog that you probably have an indexing problem. I have been using an LNL AP for 3 years, and recently experienced an indexing issue. Several months ago, I added a Hornady case feeder to my LNL. The case feeder worked fine on all calibers except 9mm (40 cal, 10 mm, 45 cal, 38 spl, and 44 mag). On 9mm, the case would not properly feed into the shell plate over 50% of the time. After adjusting the pawls many times, with little success, I finally came to the conclusion that the 9mm shell plate was the problem. I talked it over with Hornady customer service, and they agreed to send me a new 9mm shell plate for free. The new shell plate works great. So I guess the point I am trying to make is that I would try another shell plate and see if that fixes the problem prior to boxing up the whole press and sending it back.

Primer seating depth is another issue. There are several threads here on TFL which discuss LNL seating depth issues. Check the link below:
