Comparing shooting a deer to an intruder? Wow... i agree for an intruder bigger is better when your life depends on it. as for hitting an animal with a bad shot. A gut shot or hind quarter shot is a bad shot with a 243 or a 338 ultra mag. A bullet through the lungs is a dead deer with a 338 or a 243. It is an awesome deer gun. Especially for a beginner or recoil sensitive shooter. There must be a reason a 243 is legal to hunt big game with...
Best of both worlds would be the 7mm-08, same case (.308) as the .243 but a little bit larger bullet.
