Just a thought, is there a way to use the regulated sights, 100, 200, 300, to calculate the trajectory and back track to the original muzzle velocity?

Yes - but that mathematics is well beyond me (most is).
The distance between sights & their elevation above the centre of the bores gives the elevation change from leaf to leaf, range to range. This can then be applied to a computer program if the ballistic coefficient of the projectile is known. A .735" pure lead round ball has a BC of .104. That's the only one I have. Then working backwards with the program, you can then figure velocity from the elvation needed for given ranges.

Might be simpler than that - I just don't know- but the above makes sense to me.
