After having AR15 rifles, as well as a light AR10, the 5.56 rifles would be my pick for defense, due to recoil and shot to shot recovery of your sight picture. With that being said, the .308 is certainly my pick in a hunting role. Hogs, deer, coyotes will die with .22cal loads, but it’s not as reliable on game as the .30cal. Blood trails on chest shots are often iffy with the smaller caliber.
