sorry, I can't find anything with Alliant 300mp .... I did note on a chart that its burn rate is pretty much the same as H110 or W296

if the powder company can't help you, that probably means it's not really suited for the cartridge.

I've never bought that powder, so I can't even tell you what caliber it is good for.
