I have used H-108 in single shot target rifles for a cartridge called .32 Miller Short (.357 mag case tapered to .32 cal). Powder is similar to AA #9 or 4100. Yes it was sold in bulk directly from Hodgon. When I ran out, I switched to AA #9 and loads were within 0.1 gr (less for AA #9) to get the same velocity. I don't recall any load sheets included but you could ask Hodgon.
