Running quickload on your 140 ELD-M, it shows that 42.5 gr of H4350 is the max (62,000psi chamber) with a 51.5 gr water brass capacity, and the overall cartridge length of 2.8 in.
With Lapua brass though probably need to take off about 1gr though since its case capacity tends to run smaller.
With the 147 ELD-M it is 41.2 max, same pressure etc.
There is also a spec on the gas port for max pressure of ~ 12,500 psi for the AR15. I don't know if an AR10 is the same.
I helped a friend of mine get his ruger 308 AR, set up for a hog hunt he went on. He had 4 boxes of ammo from different manufactures shooting a 168 gr. bullet.
3 boxes shot fine out of his AR, the 4th was tearing the rim off his brass like crazy. The chrono was showing around a 100 fps faster in that round, and it was ejecting at ~ 1-2 oclock position. The others were betwenn 3-4 oclock.
Watch where you are ejecting and your brass condition to tell you where your max should be as you work up.
