Miller, for everything you read, you certainly do a great job of misquoting me. Where did I say that I BELIEVE that? I posted a THOMAS quote as HIS theory, not mine. But Jim's quote above is crystal clear: faster burning powder is going to recoil less if there's less of it . . . and, in the case of RD vs GD or AS, there's always less RD. And I don't believe Alliant made any statement as to WHY one feels more or less recoil with this or that powder. All they said is that their slower-burning powders recoil less . . . which contradicts the formula, if you go strictly by how much RD you use, vs GD or AS. And which contradicts what Jim posted. So you can hang with Alliant if you want, but in doing so, you seem to be contradicting . . . yourself.
