"The Firefly was not a universal remedy. The 17-pdr's HE performance was limited and at longer ranges its accuracy with the more effective sabot ammunition left a lot to be desired. Trials conducted in mid-1944 state that the useful range of APC ammunition was 900 yards (822 metres) while that of APDS was only 450 yards (411 metres). The files show that, while at 400 yards (365 metres) APC could be expected to hit a standard size target some 90.5 per cent of the time, APDS only achieved the same performance 56.6 per cent of the time. At 1,500 yards (1,371 metres), the comparative figures were 25.4 per cent and 7.1 per cent. It seems that ammunition quality improved over time, but the accuracy of the 75mm M3 gun was still admired and in demand up until the end of the war."
Those range comparisons in full..
400 yds APC hit 90.5% APDS hit 56.6%
600 yds APC hit 73.0% APDS hit 34.2%
800 yds APC hit 57.3% APDS hit 21.9%
1000 yds APC hit 45.3% APDS hit 14.9%
1500 yds APC hit 25.4% APDS hit 7.1%
