For me the Trijicon accupoint 3-9 13.4oz ~$500 is king of the whitetail woods.Realistically hunting in my part of the country shots under 100 yards are more common than those over 2 and a 400 shot is a real unusual situation.
A 223, RS light, and a nice sub 20 oz (maybe getting close to 15 oz) scope gets real attractive.
