Im gonna pick up my Pedersoli rolling block in 45-70 today and have used MVA sights on my High Wall and Sharps and was thinking Id maybe consider a MVA vintage scope for this rifle to shoot paper with.MVA has a Winchester series thats about 24" long Whats yalls opinion on vintage scopes ? Are they repeatable do- they hold up? Im assuming I will have to drill holes for the mounts.Any help and insight will be great!
