Hi My father died a couple of years ago, and my brother just gave me the Arminius HW7 that my father had. This gun came with 2 cylinders one is 22lr and the other is 22mag. I have never shot this gun but it is in very good condition. Does any body have some info on this gun, how well does it shoot, This gun has a 6 in barrel and it is ribbed. Thanks for and info.
