H110 is one of the top powders for the supers in blk out. I do use it on some loads, but not all of them. For subs, if you look at the online Hodgdon data, there are some good loads and information on what powders to use. If you follow those, it will work fine for you. Like dredd said, I won't release my load data, but it's basically right there on the Hodgdon site. I do use other powders than Hodgdon for subs that meter better or provide a slightly different burn rate than whats listed, but those will work fine for you.
