Winchester 75 heavy barrel target. I have the original peep sights but 3 years ago I replaced them with a much better set.
I have had this gun for over 30 years and from it I learned trigger control. For the first 2 years I shot 50 rounds several times a week. ½ inch groups at 50 yards are easy with it.
