Where did you hear of this 10 foot above the ground law? I looked through the entire NC Hunting Regulations booklet online and didn't find any such thing. That 770 you bought is really considered a beginners rifle and based on many comments from people that bought or still have one it will not hold up to much use without various parts breaking or wearing out because of how cheaply it is made. It should do you fine for a year or two, but if you stay with hunting I'd be looking to upgrade to a better firearm.
