The Castle Doctrine lets you assume you are in danger and lets you use deadly force. You used to have to show you were in danger. It also applies to your home, vehicle, workplace, immediate yard area around the home, and outbuildings on your property.
CC and OC are now good to go all year on gamelands in NC. You can also carry during special hunting seasons; archery, ML, and turkey.
Obviously these are quick overviews. There are a couple threads on here that cover all this better. Just do some poking around.
