Alliant 300mp loads?
The only load data I can find for this powder lists 1 load, and that's off their website. No maximum, no minimum. The loads appear to be VERY maximum, as the #'s they claim exceed those of H110's max. Does anyone have any loads they've worked with for 357, 44 and 460? I would appreciate your thoughts. I don't like the idea of my first round of "tests" being a full-bore, fire breathing, maximum. But, maybe this is a powder that only works well at the extreme end of the spectrum?
