Gamelands regs are tricky, and dumb.
If there is an open season for a game animal other than turkey, you can carry anything you want. If you are in a campsite you can carry what you want. Carrying it in your vehicle gets a bit more odd, yeah I know. During deer season most of the gamewardens frown on carrying loaded rifles. Any time of the year you can carry a .22 pistol with a barrel less than 7.5", OC or CC. That's the official take.
I've had at least 2 wardens tell me "you should be fine if it's in your backpack while hiking". Not sure I trust that though.
There used to be an exception for a shotgun with smaller than #4 shot. That seems to have been removed though.

Weapons on Game Lands
It is unlawful to possess a firearm or bow and arrow on a game land at any time except:
1. During the open hunting seasons or hunting days for game birds (which are waterfowl, doves, woodcock; snipe, rails, gallinules, moorhens, coots, grouse, pheasant, quail and turkey) or game animals (which are deer, bear, rabbits, squirrels, wild boar, bobcats, opossum and raccoon) other than fox;
2. Unless the device is cased or not immediately available for use;
3. When possessed and used by persons participating in field trials on field trial areas;
4. When possessed and used on target shooting areas designated by the landowner;
5. When possessed in designated camping areas for defense of persons and property
However, .22 caliber pistols with barrels not greater than seven and one-half inches in length and shooting only short, long, or long rifle ammunition may be carried as side arms on game lands at any time other than by hunters during the special bow and arrow and muzzle‑loading firearms deer hunting seasons and by individuals training dogs during closed season without field trial authorization.
Furthermore, only shotguns with any size shot and bow and arrow may be possessed during the big game season for turkey.
Previously, you were limited to a shotgun shell no larger than no. 4 and rifle or pistol no larger than .22 rimfire when the big game seasons were closed. By adopting H29, the Commission is allowing hunters to possess more powerful weapons during small game and migratory bird seasons, in addition to their possession during big game seasons, with the exception of turkey season (no handguns and no rifles).
