I was pleasantly ignorant about my rifle bore conditions prior to the internet. Now I wonder if I have a carbon ring, residual copper fouling, etc.... I load for my rifles for hunting but enjoy the process and challenges. Is a borescope a helpful tool for occasional use or is it mainly a tool for competitive shooters and gun dealers? See that the Lyman digital scope is only a couple of hundred dollars. Would it show a carbon ring. Is it a decent product? If threw down the money for a Hawkeye, would it be more useful as a regular part of my cleaning regimen? I really want to know if I have carbon rings. Can these be isolated without a borescope. Should one just assume a carbon ring is present and scrub away at it?
