Actually, fnb, I've never seen a formula for recoil that takes acceleration into account. The guys that go by "you have to be able to measure it" haven't plugged that factor into any formula I'm aware of. Now I'm willing to accept that acceleration may indeed matter. And in fact, if the "less felt recoil" stuff is true, it's got to be as a result of something other than just ejecta weight, because there's always more of the slower burning stuff (assuming it really does recoil less) than there is of the faster burning stuff. But assuming said difference is MEASURABLE rather than just FELT (which is subjective), then there's got to be a formula to calculate it . . . right? Do you have one?
