Default 9mm - Why 115, 124, or 147 grain

Hello, All!

I am curious about the history of how the bullet weights for 9mm and other calibers were established. Why 124, instead of 125? (Yes, I know there are some 125s out there.) Why 147, instead of 145 or 150? 38 spls are usually 148 or 158. Why not 150 or 160?

Like I said, I'm just curious how those became the standards. Anyone know the history?

Thanks!

GB.
