Also about the transfer, I remember reading something about weapons have to be transported in the backseat of the car uncovered. Is it true? How about carrying from the car to the house/shop?
The shotgun is Mossberg 12 gauge 3 1/2" chamber 835 ulti-mag
The rifle is Marlin centerfire level action rifle with a riflescope.
Don't do that. Put the firearms in a case if you can.. unloaded if you don't have a trunk.
