Can't tell you too much, other my father gave me one he acquired from a neighbor. I did research the manufacture date, but can't recall at the moment what it was. Anyway, I refinished the stock myself, and had it professionally hot blued. I reload for it...Hornady RN 60 gr I think...would have to go look and see what the powder is. It's fun for plinking at ranges under 100 yards...best bullet speeds are well under 2000 fps. Might make an OK small game rifle if shots were kept within reasonable ranges. Mine has an octogan barrel...maybe they all do? Hopefully you'll hear from someone who can provide the info you're looking for.
