Video answer: 223 -vs- 5.56: facts and myths
Top best answers to the question «Should 5.56 rounds be used for deer hunting»
With proper loadings it's usable up to deer. It's great for smaller game (hogs/coyotes/etc) A bit overkill for very small game (rabbits/Prairie dogs/etc) but it's often used for them with lighter bullets where ranges are long and you need some extra reach. It isn't generally considered to be acceptable for larger game.
223/5.56 as a deer hunting caliber. While shots should still be limited to ranges maxing out at around 100 yards (the small bullet just sheds too much energy beyond that range), hunters can now feel confident in taking their rifles afield during deer season.
