Was raised to shoot for double lung and still today that is my objective. I have dropped down slightly to take a heart shot when possible and with a 25-06 and Berger bullets (I know I'm not getting an exit past 50 yards or so) I've never had one go more than 50 yards. Down here in SC I'll pass on a shoulder shot...deer are small enough already and throwing a front quarter away drops the meat take even lower. Elk, moose and mountains might make me change my mind but sticking with with heart/lungs for now.
