TO: Commanding General, Twelfth Army Group. 1. The board convened pursuant to the attached order at the firing range established by First U.S. Army near Isigny, France at 1030 hours, 19 August 1944 and conducted firing tests against the front plate of German Panther Tanks. The firing was continued, as the weather and the availability of target tanks permitted, on 20 and 21 August 1944. Because of the urgency of the test, a preliminary report, dated 21 August 1944, was submitted on 22 August 1944. </TD></TR></TBODY></TABLE></CENTER> The 17pdr guns were fired by two superior British enlisted gunners. The 76mm gun was fired by two officers with considerable test firing experience. Forty-two (42) rounds of 17pdr SABOT were fired and only 57% [24 rounds] were hits. Firing was done at between 200 and 600 yards at a stationary Panther. It was suggested that the APDS ammunition was sub-standard. Does anybody have any information on either the accuracy of the APDS round or how widespread it's use was after it's introduction in August '44 please?
