I have known a lot of people who have harvested TX whitetails with the .223. And it is fine for feral hogs, Russian boars are a different story. The previous post about Russian boars are accurate and then some. These animals are very large and the way that they are built, makes them better protected and stronger than animals twice their size. We quite often find old bullets (even .30 caliber) gristled over in Russian boars that we kill.
