I'll go out on a limb and predict that none of the mentioned loads will punch through the concrete block (capstone?) at 500 meters.
That is, if by "M118" LRRP means M118LR (175gr SMK). However, M118SB (173gr FMJ) is the one 7.62 load that I'd expect to get through.
For 6.5 Grendel, I think it'll require 139-144gr FMJ.
