So far,we have been working with opinions. So I did a little research.
I would directly cut and paste,but I understand that can be a copyright issue.

If you go to the article,check the "History" topic,move down to the last paragraph that begins with "Wartime production was about...." and read till he topic changes to "Weapons"

The article specifically addresses the problem of the 178 gr boat tail having a max range of over 5000 yds and overshooting ranges. The bullet /load was redesigned for approx 3600 yd max range to solve the problem.

This is given as the reason for the redesign/switch from " Ball M1 " to Ball M-2" approx 1938.
