I got a new Lee Pro 1000 a couple of weeks ago. I have not had the kinds of issues many of the Midway and Cabela's web site reviewers have had.

I am seeing one issue though: During initial setup I'm just doing one round at a time until I get the powder drop and bullet seating where I want them. When everything looks good, I go into "progressive mode" and my OAL shifts .020. If I adjust from there things stay consistent through the run except for the last two rounds which shift back .020.

So it seems the OAL varies .020 depending on whether or not there's brass in the resizing die. I'm using Lee dies (.40 S&W and 9mm) which are screwed in just enough to touch the shellplate. I'm thinking this may be a matter of either screwing the resizing dies in more (or maybe less?) in order to get a more consistent stopping point for the stroke. I'm thinking the shell carrier assembly of the Pro 1000 isn't going to be as indestructible as the bottom end of my LnL single stage press so I'm looking for advice before cranking it down.
