The loading manuals typically list a round at SAAMI max OAL. Typically that has nothing to do with what will shoot best in any particular rifle. I generally start .010" off the lands OR at the max magazine length and work from there. You've already determined that you can't touch the lands at your magazine length of 2.400", that's where I would start. Since you're at max magazine length you've only got one way to adjust when you start fine tuning seating depth.
While it's not always true that a bullet will shoot better with less jump, I've found that most often they do. That 2.350" basically means nothing.
