Ive been hearing a lot of stuff about the 7mm mag.And every time i hear something about it i haft to disagree.Ive tried it and didnt like it because every time i shot a deer it ran50 yards or more.I even shot one in the head and it got back up with half of it head blown off.I didnt like this so i switched to a 30-06 with 180 grain sp core locks and every deer ive shot with itdrop in a heap and never moved.So basicly what im asking is this normal for a 7mm mag or is it the bullets im using?thanks
