I am mounting a shotgun on my ATV with the barrel facing up for various reasons. The main reason is me not wanting to "rake" anyone I drive by like it would when mounted in the horizontal position. Mounted vertical, I am concerned about debris falling in the barrel. I remember seeing covers that go on the ends of long guns that are simply blown out with the first shot. Is there something special about these covers or would a child's balloon accomplish the same results? My concern is chamber pressure and marking the finish on a parkerized gun.
