Isn't this what is usually referred to as HESH - High Explosive Squash
Head? A round that squidges against the target on impact, then detonates
and sends a shockwave through the armour, causing chunks and splinters
to
spall off the inner face and do a Magimix job on the unfortunate
crewmen.

IIRC (and my knowledge on this is rusty), they are not particularly
velocity-dependant and were thus used quite a bit for lower velocity
guns
such as the old 76mm on the Scorpion CVR(T). I think their range and
accuracy is relatively poor, but when they hit they can be quite
effective
killers.
