Max load is 51.5 in both my rifles with 3.220 OAL. One loves it the other hates it. Velocity is a hair over 3000. My most accurate load in the one that likes it is 49.5 grains, Fed 210M primer, Lapua brass. From that rifle with only a 23 inch barrel velocity with this load runs about 2870.
My Lapua brass and 139 grain Scenars should be in by Wednesday or so. I have a couple hundred GM210M's left too.
The reason I want to use H100V is because it works great in my 6mm284 and 338 WM. I think it will work okay in the old lady's 7mm RM too. How nice would it be to have one powder for four cartridges.....
