Sorry it took me a few days to get back to you. Hopefully this helps.
I set the max pressure to 55kpsi which is about 7,000psi under SAAMI MAP of 62kpsi. This builds in a margin of safety. I do not know how sensitive your gas system is (assuming this is an AR-10) so the powders that make the top of the list may or may not be suitable for reliable cycling.
I used an NOE bullet mold that is similar to the bullets you are showing. I had to manually adjust the bullet weight to 690gr, despite this the bullet is listed at 694gr just be aware that I did run it at 690 and the results are at 690 not 694 as listed on the sheet. You should be able to go to the NOE website and look up the bullet mold that is listed on the sheet and compare it to your bullet.
I assumed the barrel length is 16" so all velocities are based off a 16" barrel.
