You are not alone in odd rules on what you can use.
Here in Florida during the "small game season", when hogs are still legal and when you can use rifled shotguns and pistols ( any caliber! ) and muzzle loaders, I can't take my .35 Rem.......
This is on WMAs.........private land is different.
It's a old regulation that needs updating.
Of course the issue of HUNTER ORANGE not being mandatory during the small game season also needs updating even if the rifle regulations are not changed.
