However, since you appear intent on chasing your tail about this, I wish you the best of luck

Puppies have been known to do that from time to time.

Not sure if this helps, but this is what I use for 9mm............

I bought three books with stuff like that in them. Their writings make about as much sense as my pondering of case volumes does with others.

Hey! You stole my calculations for windage adjustments to compensate for the earth's rotation when shooting to the north or south!

If I followed the math correctly I'm pretty sure that this one is the calculous used when shooting parallel to the equator, either east or west, as to whether one should use a right or left had rifleling twist (determined as to whether they are above or below it) to help the bullet counter the gravitational pull in order to keep it (the bullet) flying in a straight line.

. . . and you forgot to "carry the 2".

'45COLT'---the case was designed to hold a fairly large amount of black powder. Depending on the 'strength' of your revolver, using a recommended amount of smokeless powder fills a relatively small amount of this space. Therefore, the difference in amount of 'excess space' will not have a large influence on the overall outcome of the loading. Combined with the reality that most '45 Colt' revolvers aren't specifically intended to be tack drivers, it's very unlikely that a small variation in internal case volume will result in noticeable accuracy improvement/degradation.
