The 7,5cm 40/42 does not require a Cap (other than the Ballistic) as it uses a sleeve made from Preßstoff to mitigate shock to the penetrator. Caps were originally used to conform the target surface thereby improving Energy Transfer and as such penetration. The Squashing "surface stretch" principle for Hardface removal is fascinating science for itself but as far as I'm aware the R&D wasn't far enough in 1939-1942 to claim it as the purpose of a "Sharp edged" Cap on a pre 1939 Design.

The intended functions on impact and the parallel advances for AP's are as different from another as the physics surrounding them. So... There's still a Kiste Weizen down here waiting for you... Come on down we can carry this on in more applicable conditions
Oh, you sweet talking bas*@rd. How can I refuse, I have already cleared a couple of weeks co-operative training with the new job. When C in C Domestic has retired we shall be over, (that means she can baby sit and we discuss more important matters).
