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.

Guys, I have seen it many times. This is a very dynamic load in many guns. Anywhere betweent 93.5-95 has worked in probably 5 guns I have seen. Mossy substituted partitions for the accubonds but same result. It won't hit 3300fps but will definately work.

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.

increase barrel life dramatically
How about providing us with some test data gathered with two equal barrels and cartridges that demonstrate just how much the use of this powder will increase barrel life.I accept actual data much more readily than theories.Then again you are assuming that all guns will provide optimum accuracy with this one powder which is certainly not likely to happen.

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.
