Well, HEAT isn't particularly velocity dependent either, most slow
tank-killer grenades/rockets/shells use that. HESH likes to be
rifled, HEAT doesn't. HESH is, I think, preferred for knocking holes in
concrete fortifications.

IIRC, the record for the longest confirmed tank vs. tank kill comes from 120mm
HESH being used in operation Desert Noun, at something like 6,000 metres.
APDSFS would have a flatter trajectory and be more accurate, but the longer
the range, the lesser the penetration.

My understanding was that HESH was the British nomenclature. The US used the
term "HEP" although for
at least the past 30-40 years the only HEP round in
use was the 165mm demo gun round.

In the US Army it's called HEP - High Explosive Plastic.  They can be
very effective, but they are extremely unreliable, because the actual effect
on the target is highly variable. A standard "party piece" at various
demonstrations was to trot out a bushel basket full of fragments collected
from a HEP hit on a target hulk. What nobody ever mentioned was how many
shots it took to get one that produced THAT effect. HEP/HESH is  very
effective against concrete, however, and that was it's main use by doctrine
(in the 70's anyhow) in the US Army.

One of the problems with answering mail at 2 AM in the morning is that you
write one thing and meant another. It is not APSH but HESH (HEP) that I meant.
I was not commenting on how
effective it was but only that an E/M field would cause very little
dsiruption to this type of round.
