I'd very much like to see the source that claims the 17pdr to have a 98% chance of hitting a 6x6 ft target at 1000y with the APDS round, let alone the APBC round! IT DOESN'T EXIST!
And a 80% hit rate against a 6x6 ft target at 2000y sounds like a load of BS in my ears, even with the std. APBC round.
Regarding the shattering of the projectile: Read Thomas L. Jentz books on the Tiger where numerous incidents of this happening are cited, and read Robert D. Livingston Lorrin R. Bird's book "WW2 armor Gunnery" where the so called "shatter-gap" is explained in detail.
