Crows are very very intelligent, usually. Nobble one of a pair with a rifle and you might get the second within a few minutes if you have not been spotted but after that the survivor has gone. I had a pair on Sunday like that, hit the first hard, it flew off over some power wires with its mate with what looked like its head between its legs. Went round to the next field to find a single crow at about 150 yards, perhaps a bit more on some drilled barley. Tipped that over with a 20gr Vmax (17AH), sent the lab for it, she stopped en route and brought the first one back that was laying in a bit of dead ground. Hit low all its backend was hanging out, massive damage yet it flew 150 yards or so.
