I had a couple of rifles scoped by my gunsmith recently and took my 336 .35 Rem in to him as well & he boresighted it in with a Skinner Lo-Pro. When I went to pick it up he had moved the front sight somewhat, not much - just enough to be noticeable if you eyeballed it. I'm not going to doubt him though, he's been smithing for over 60 years now and is "the man" according to most around here. Even so, wondering if anyone has done the same. This is my first lever gun, haven't got a chance to shoot yet due to work/weather.
