Hi,
The picture below extracted from "Challenger 1 armament training pamphlet" from 1945 shows a HE projectile different from those in this thread (fert and rickwedlock)
Is is just because it's a poor drawing, or is it a different variant ?

Very surprising that there is no APDS pictured in the manual (or is it on a separate page?). Maybe they just forgot to update the ammo section when they reprinted it?
