Do you guys think a 223 is OK for whitetail at closer distances, say 150 yards and less? I hunt in Central Texas where shots are usually between 60 and 150 yards, and the deer are not large. I really like the 223, but have mixed feelings on the ethics for me to shoot such a small caliber for deer. Again, my dilemma over the ethics of it is for me. I'm not casting aspersions on others. Thanks!
