I shoot both magnums and non magnums. I have never been engrossed in the way of thinking it takes that added ft lbs to kill an animal. I have several rifles that will take out a pepsi bottle at 600 yards with a good set of bi pods and good conditions. I'd rather spend my time worrying about accuracy and my loads, the rest is threading the needle. It don't take a magnum to kill but if it's accurate in your hands then why not.
