Did I hear 7mm STW? Well that is a cartridge which I am rather fond of and I have built many of them. That H1000 seems to be one of the best powders for it and most of the rifles I have seen or built chambered for it work out best for accuracy/ velosity right around that 85 to 86 grain load. It also seem to be rather mild on recoil for what it is but that is probably just my perseption. However it is mild enough so that most experianced can put in enough time with it to shoot well.
