For example the Bohlers had a distinctly lower MV for the HE rounds, and the figure is for the AP round.


The HE round is much much larger at about 2.5kg as opposed to 1.45kg. It looks very strange as well. The projectile is long and blunt nosed. I think they disposed of ballistics in favour of ramming in more explosive power.

I mentioned the Bohlers because there is a drop off of several hundred m/s between the AP (630m/s) and HE (250m/s), for the reasons RA stated.

While seeing a slightly heavier HE round with somewhat lower MV is common, the Bohler seemed to be extreme.

Details can be found here. The HE projectile is about twice as long.

Just a brief engineering comment when drawing tanks. Remember that when you design "sim" tanks, that in the real world the main tank armor is concentrated forward in the glacis and mantlet. This means if you shove that gun too far over the glacis, you are going to have a nose diver tank that is going to bog down as it tries to cross muddy or soft ground as it will have too much weight forward of its center of mass.

It actually becomes a plow. It will get stuck. This was a historically little noticed design defect of the original prototype Panther and the T-34 until German and Russian engineers either moved the turret to midhull and or added some rear countermass to balance the hull on its tracklayer.
