Hey Mossy,
Your concerns are valid. Your buddy, as your hunting partner, must take them seriously and address them appropriately. If he chooses to either ignore you or treat you with anything but respect, forget about him. And consider yourself ahead of the game for finding out "how things are", now, before someone gets hurt. If your friend is really someone worth having around your deer camp, he will undoubtedly come through for you here and he will respect you for having the guts to confront him. I've been in your shoes and have seen both outcomes come to fruition. Good luck man.
