I have a couple of instruction videos re Hershel House, and I believe that he uses straight linseed oil as a finish on his rifles. Can anyone varify this? I've heard time and again that this is not a good finish, and I haven't used it, but have used "Tried and True" varnish oil. It worked out well, but I haven't used the gun enough to see how well it stands up. I really like the look of his guns, so if it works for him.....?
