thanks for all the input, comarades. Right now I am using impact and having success but this is only becuase I can get away with setting up within 1000 meters and 90 aob to the target. I tend to try to sink ships with only 1 fish. later in the war, i dont think this will be possible. I am thinking that when I need to shoot at 1500 - 2000 meters range at a full spread i will want to use magnetics and still achieve the 1 shot, 1 kill result. I hope I 'have a little Captain' in me, and his name is Kretschmer
