11,000+ APDS rounds sounds fired by US forces sounds like a lot of trading unofficially. I am sure it was supplied openly. The figures came from research that ASL guru Bob McNamara did at Aberdeen PG - I think. The 6-pdr APCR round was found to be "balistically unstable" and was not used in NW Europe but might have been used by some British units in the last month of the Tunisian campaign, for example at Longstop hill, as there is reference to a new AP type round in the action reports, and some sources (Fletcher's book on the Churchill published as Mr Churchill's Tank) also mentions an "HVAP" round (horribly vague, imprecise term) being issued to some Churchill units.

6-pdr APDS figures dug out - 1st US Army fired 6302 rounds June-July 1944, and 11,428 by VE Day. 5th US rmy in Italy got APDS in December 1944 and fired 180 rounds by VE Day.
