Well this does not work every time by any means, but does work often enough to be worth trying...it is a trick I use often when hunting with flintlock and now and then with a .22
prowl through brush, briars whatever...rabbits like heavy cover...until you jump one...as the rabbit takes off...put your gun to your shoulder..tracking him but don't fire and don't move! Not an inch! The rabbit will run off, but if they get no sense of being pursued, often stop and look back after short runs.....and that is when you fire!
