I can't help with a load for the 75gr Hornady but I use 77gr SMK in mine and found N140 wouldn't get decent speeds with the heavier bullets as the powder was compressed with 22.4gr in the case so I couldn't get up to the next node (just over 2400 fps but great groups), I've used both RS40 & RS52 with much better results (22.8gr giving 2830 fps and still not compressed), there's probably a Vhit equivalent but I'm not sure what it is and I can get my hands on RS powders easier.
The numbers above aren't any use for the load that you're developing for BUT you can see the capacity\speed difference between powders, Reload Swiss has a good website with their load guide.
