I shot 100V in my 700, 243 with 80g Sierra's.
42.3g in a Win case with a Win primer, shot extremely tiny groups. I believe that the groups were the smallest that I have shot with any sporter including the many 788's that I have had in 222 and 223. Groups constantly less than 1/2" at 200 are not bad.
My Brother's rem 700 shot the same load shooting clover leafs with the bullets always touching. I went to the gun shop and bought the last 3 lbs he had, all of the same lot that I had tried.
My regular load of IMR 4064 with the Sierra80s was great, but this 100V has got it beat by a country mile, and fast also.
I was letting the barrel cool down in front of the AC, When a crow lit in a tree at 300, just off to the side of the 300 yd berm, turned him into a gut ball.
I'm going to try the 70's next, just for grins.
