Bring the P-47M down to 6 guns and 247 rounds per gun and I promise it won't be used as much. Most of the random MA folk that buy into the hype about it don't really understand it. Those few that understand the plane won't suffer if it receives historical weapons loadouts, but the rest would drop back to the P-47N (which also shouldn't have the overload ammo) or the D11.
Only one group of late P-47Ds had the overload ammo and that was only when they weren't carrying bombs and rockets and only for when they were strafing many ground targets. It was not a normal combat load and the D11, D25, M, and N never carried it.
Thus endeth the side-track.
