Interesting. I wonder if there ever was a physical way to measure it as well. I guess someone at some point did and then proved the formula.
Thanks,

I would imagine some nerd put an accelerometer on a gun once and proved the theory.
@Philip Glass since you were unaware of the formula, its worthy to point out the one magical part of the formula most people don’t know. All other variables being equal, the powder that does the work in the fewest grains will have the least recoil. For example, a 470 Nitro using IMR4350 might output 89lbs of recoil, but by simply switching to Reloader 15 the recoil would be 68lbs.
I myself am a huge recoil sissy and therefore am dealing with this now. I have a 470 that will regulate perfectly at 50 yards, as in the bullets are the width apart as the barrel wedge with IMR4831 using 107gr of powder. (Ouch, ouch) Or I can settle for about 1”-1.5” groups with IMR3031 using 77gr of powder instead. The former is about 80lbs of recoil, the latter is only 58lbs! (the latter regulates at 50lbs slower speed so the contrast is greater)
