Swapping rounds?

I have half of a Tamiya german tank ammo-loading crew left. Thing is I’ve done two German tanks and would like to try something different.
I have got all the Pz.Kpfw IV rounds and ammo crates left and was wondering what other vehicles would have used this round?
I’ve also got the King Tiger rounds left aswell, but I imagine it was the only vehicle that could use this round.
While we’re on the subject, does anyone know if axis and allies rounds were interchangable? Wouldn’t it be cool to do some Germans raiding a knocked out enemy tank for ammo and supplies?
What is everyones thoughts on this?

You could swap rounds between vehicles with the same main gun. Some German vehicles used the same main armament but you’d have to do a little bit of research to determine which ones.

Swapping between Axis and Allies wouldn’t work … very different.
