The reason why I said over kill. Is because out in the woods where the deer are you will be lucky to get a clear 75 yard or longer shot. My old 20 at 50 yards left an entry and exit wound, then imbedded into the tree behind it. he actully jumped and room about 10 strides then fell right in front of my stand. Dead within seconds. I hit his lungs and ruptured his heart. A perfect shot. The 12 just isn't needed unless you want 100+ yards. But like I said where in the wood will you get that shot?
