I had listed 19gr of h110 to try for about 1000 fps with my 10.5″ barrel. In quickload it shows a burn % of 96-97% in a 10.5″ barrel. I had a friend run some numbers for me, so YMMV, use at your own risk of course. I have not tried this load yet. Load worked up in Quickload with a 2.150 overall length.
