Not really in this case. The standard 75mm Sherman gun shell case just didn't hold enough "umph", which is why they went to the 17-pounder (76.2mm), which did. The Americans later went to the to 76mm gun, which of course did as well, albeit perhaps not quite as well, hence the adoption of the 90mm later. The original 75mm was good in 1942 but that was the end of its service life except in extraordinary circumstances.
