Stielgranate

[Kiwikkiwik]

I found something relevant about Stielgranate that might be useful, a quote from Andersons The History of the PanzerJager

from Von Mullers information leaflet on the munition

Its most effective combat range is less than 130m, but under exceptional circumstances a stationary target can be defeated at up to 250m range.

From an after action report,

The first tank was hit at 150m range, the second at 100m.

and

It is important to keep the Stielgranate well hidden until the target comes within 300m. Beyond this point the tank can easily destroy the gun.

I don't know but I imagine that the 5cm blank cartridge being bigger than the 3.7cm would have meant the 5cm gun would shoot the Stielgranate faster, further and so would have a better effective range than the same munition on the 3.7cm gun. I don't know if the reports above refer to 3.7cm, 5cm or both.
