Are those powders the only ones you have to use? Or are you open to considering something faster?
I would vote H4350 is the best on your list (it's what I use out of your options, and I have them all), but the list is skewed to the slow side for the case. Quickly running through my notes and the Hodgdon 100gn data shows that Hybrid 100V will run faster than H1000 at a lower charge weight, Varget will run 4%/ 100 FPS slower with 70% of the H1000 charge weight, and H414 runs the fastest.
I use H4350, IMR 4831 and Varget with similar bullets to yours, 90gn Nosler BTs and 100gn Sierra HBPTs. 26" 1-9.125" twist varmint profile.
