I have been in contact with the NCWRC and Jones County Game Warden and both contacts (one in writing and one via phone) have stated that it is LEGAL to mentor and call for other hunters, after you have filled your tags, as long as you are not in possession of a firearm or ammo. The Game Warden stated that as long as you weren't in possession of the gun and weren't carrying any ammo, he was fine with the mentoring and calling for other people. As a matter of fact the Game Warden stated he encourages the mentoring of other hunters, whether kids or adults, because mentoring encourages others to participate in this sport and enjoy the outdoors.
As far as the TAKING issue, in this case, the Game Warden stated that as long as you aren't in possession of the firearm or ammo there wouldn't be any citation issued. I agree, there seems to be some GRAY area in the TAKING issue but he did state to me over the phone that he had filled his tags for the year and he was mentoring as well.
So in the state of North Carolina it appears that you are not in violation of the LAW, in this case, unless you are in POSSESSION of the firearm and ammo.
The way this sounds to me, it's like driving 5 MPH over the speed limit and not being issued a citation. You are in fact breaking the law but the officer chooses not to stop you until it reaches 10 MPH over.
