I can't see anything on any of my old brass, or inside the gun. Gave the rifle a good cleaning today and still no luck. Forced a piece of brass in and these are the marks it leaves, almost flat. Guessing I will have to find a local smith to bring it in
I will get a bore scope ordered. It is factory ammo and was fired from the same rifle, I only tried the brass so it would be safer to force it some than a live round. I do not have a go gauge either. Just to rule it out I removed the scope mount and stock but same issue. I have every piece of brass fired since I have owned it, wouldn't I notice looking at the brass if one separated?
