If you have a bunch that shoot well, try shooting those in different temperature conditions. See if one is less subject to change due to temperature fluctuations. Another factor is powder availability and cost. A load that is #2 by a small margin is preferable to a great load with a powder that you can't get or that is $100/pound.
When you say it was too long for the new chamber by .005", was that at the shoulder (headspace), or the COAL? If it was COAL, why not just reseat the bullet a little deeper?
I'm guessing that a 28" barrel is going to be a target rifle, so maybe temp variations won't be too extreme, but target shooting is a little more demanding of the precision aspect, so a quarter MOA matters.
