Do you have your CHL? You must have one to carry while hunting in a national forest or in the VA wildlife management areas. But I believe you must conceal while you are there.
The different localities shouldn't have the power to regulate you carrying your sidearm because of state preemption. But they can regulate what you are "hunting with." So perhaps those local laws about revolvers etc are about hunting with your handgun instead of a rifle/shotgun.
I had a debate about it for hunting during bow/muzzleloader season - because you aren't allowed to have a firearm with you, unless you have a CHP.
"Concealed handguns may be in the possession of hunters during the archery and muzzleloading seasons when they also possess a valid concealed handgun permit. Such handguns may not be used to shoot wild animals during these seasons."
So I may not have answered your question and possibly confused you more. In general, if you have a CHP and conceal then there's nothing stopping you. As far as OC, in my Unprofessional opinion, it seems to be legal during non-archery/muzzleloading seasons and when not in the restricted/concealed-only areas. But you have to be careful because a picky game warden could accuse you of hunting with your handgun that may be against local laws..
