Mossberg 835 shotgun, with Black Diamond scope. i have 2 interchangeable barrels for it... shoots 3.5 inch magnum, in 12 gauge... The picture below is of the same gun. I can swap barrels, and use the scoped, rifled barrel for deer, & shotgun barrel for turkeys.
I have slayed both turkeys & deer with it... the 3.5 inch mag shells are super.
