LLoyd,
Timing with the LNL is, of course, a critical set up. While hornady sets them up close at the factory, mine needed tweaking. What I have found is that the advance pawls should be set to where the plate is just falling into the detents. This applies both directions (both pawls). It is a critical adjustment in that, if you move too far, you can get out of time the other way. Once I figured this out, and took my time setting it up perfectly, the machine is virtually flawless. Unless a piece of crimped brass sneaks its way onto my press, I can load virtually without stopping for anything other than primer and powder fill.
