I have some .223s loaded up with 55-gr TTSXs, but for serious hunting or defense, I load the 60-gr Nosler Partition. It's scary accurate out of both of my ARs - one-hole groups at 25 yds. I shoot 12-ga hulls off of target stands at 100 yds with them. (Too bad they're $$$!)

Violence is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and valorous feeling which believes that nothing is worth violence is much worse. Those who have nothing for which they are willing to fight; nothing they care about more than their own craven apathy; are miserable creatures who have no chance of being free, unless made and kept so by the valor of those better than themselves. Gary L. Griffiths (Paraphrasing John Stuart Mill)
