Rather than resurrect a thread from back in August I thought I'd just start a new one. Someone was looking for information on wether the B-25's ever loaded anything other than HE on the 75mm cannon. I just picked up a copy of "B-25 Mitchell Units of the MTO" from Osprey. While I don't expect this anecdotal evidence to change anything I thought I'd post it for those who may be interested.
"[Talking about the B-25G] I was in an attack at sea, but against Panzers it was rare that we got off two rounds. But one round usually did the trick, with pieces of the tank flying high into the air. When the shaped-charge shells like those 75mm brutes we used hit a tank, it blew it up from the inside out."
and
"Those 75mm cannon rounds were 26 inches long and weighed some 20lbs each. Just above the cannon breech was a rack that held 20 rounds. We carried mostly high explosive warhead rounds, with a few armor piercing shells thrown in for good measure just in case we me one or more of the dreaded German destroyers prevalent in the area."
"The cannon was a standard M4, with a specially constructed spring to absorb some of its recoil shock."
