I think Bore scopes have their place. I agree one can get over concerned at what you see compared to accuracy. In saying that I use mine when I buy a rifle ( can see damage, rust, copper fouling, throat erosion etc). It’s also very useful to check things like scope base screw protrusion in to the chamber.
