Accuracy with multiple main guns

[Kuad]

I've noticed that multi-turreted tanks like the Char 1-bis and the Lee/Grant seem to be quite a bit more accurate with their large bore HE guns than their AT weapons. Is this historically accurate? From looking at the Grant, I'd think it was a helluva lot harder to aim the 75mm than the 37mm. The damn things have managed to get more kills with the "infantry support" gun vs. tanks than the "AT" gun.

Bugger. How'd that happen? Admins, please delete the dupe post.
