Perhaps I should have been little more specific. I'm playing at 100% realism using the tools offered in the game only (distance using mast height, speed using 3:15 rule, no WO help). I'm only at 1940 with TIs and TIIs. I have yet to intercept a convoy but I'll worry about that later. I still find it hard to believe that people actually score a hit at 3000m or beyond (unless it's using a homing guidance). I think the biggest issue for me is finding the exact distance of the enemy ship. Especially when the water is rough whenever I plot the target's course it looks like a mess and doesn't represent anything close to a line. But then again I have missed a target at a distance of 500m when the water was like a mirror :damn:.

Between 1500, to 800 meters is my usual launching range. I have fired at over 5000 meters and hit and sunk a target, but that was a rare shot. I do sometimes fire at ranges of 500 to 300 meters, but only in poorer conditions.

For me,

39-40 400-1000m
40-42 900-1500m
43-44 2500-3200m
44-End of the war 3000-5000m

I try for 1200-800 range. I have done it at longer distances but only as a last resort.

Usuallly anywhere from 500-1000 metres...or closer but of course never any closer than 300m or the torps dont arm.
