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.
