Taw. I'm reloading 95 grains of H1000 with the 180 grain Nosler Partition. I worked up from 91 or 92 grains to include 96 grains (max load). I got a bit tighter group with the 95 grain load. I'm shooting minute of angle at 100 yards with a 700 BDL. Have also gotten about the same with IMR 7828, but I don't have that load data handy at themoment.

Shoot a 5 shot group with the H1000 rounds
I don't shoot 5 shot groups with my ultramags or my 7mmstw's.I also don't normally shoot h-1000 although I have tested it in my guns.I keep my barrels from heating up by limiting my groups to 3 shots and I do not normally shoot in hot weather.My barrels are also of heavier than normal contours and are fluted.

Stubblejumper - this stuff that Ridge Runner is posting is considered common knowledge among ballistics engineers. I know its good to ask questions and request quantifiable proof; but he really isn't out on any sort of limb here.
