Again you aren't proving anything.So, you are stating that they will selectively tailor a propellant to specific bullets, but will not do the same for ammunition and weapons?
If you can select a propellant type that is less erosive, but has a slightly higher muzzle pressure and isn't quite as accurate, you would not load that in belts? Or, if you have a lot of ammunition that has a higher than desired muzzle pressure, you would load that in clips for M1s?
I have provided the evidence and the reasoning behind it, but feel free to believe what you want.
Your chart shows both types of M2 ball loaded with the same revision number of powder. Hence it's the same. M2 ball is still M2 ball.
Considering we don't the difference in the various revision numbers..we can only speculate.
However considering all the different cartridges you listed are "different" the powder charge will also be different.
But anyways you have drifted way of the OP original question.
