RE: Shotgun only states???
Massachusetts is a shotgun only state as well.
You can use an inline muzzleloaderduring shotgun and muzzleloader season though which sort of contradicts the no rifle rule IMO. You'reeven allowed to use a hinge action muzzleloader during the shotgun season. I know you only get one shot, but with a good muzzleloaderand a good scope you're shooting a high powered rifle and only need the one shot IMO. I've been leaving the shotgun at home and using the inline when I hunt from my treestands.
