As lawyers like to say, the fact is: The ejecta all goes out the barrel in such a short time, different rates of acceleration are not detectable by the shooter. Therefore, the burning rate of the powder used is not a factor, only the weight of the powder charge. (maybe that's why burning rate of powder is not in the recoil formulas, nor is pressure, ya think?)

As always, nothing ever changes, neither minds nor more importantly, physics.
Good post, EDM.
Always fun
