I'd be very surprised if it is really rust. If you really want to know, go find a gun smith or someone with a bore scope. Bore scope it a see for sure.
I got some of the live rust off and it is pitted underneath. You can see some of it an eighth inch below the muzzle. It is definitely rust.
Well, that sucks!! Just curious, have you shot it yet?
No, I didn't shoot it. I talked to one of the managers at Cabela's gun library and he said to wait until all of the Black Friday/Cyber Monday craziness was over and bring it in to show them the problem and they would see if they can get Savage to service it, otherwise I'd have to deal with Savage personally and handle all of the shipping costs etc. So, I brought it in last Thursday. The first guy I talked to acted like he was skeptical that I had even spoken to a manager before, let alone that one said to bring the gun back in. He told me that he couldn't help me and said to talk to one of the other guys at the counter.
The counter employee called someone in back, who it seemed works on getting factory work done on guns that Cabela's has in stock. The third employee, was the only one who took the time to actually look at what I was talking about and seemed concerned. Luckily, being a precision shooter, he was equally dismayed at rust and pitting in a brand new barrel. He said not to worry about it, filled out some paperwork instructing Savage not to attempt fixing the bore but just to replace the barrel, gave me a service slip, and said turn-around is usually 3-5 weeks. Then we talked about guns for a bit. I guess it all depends on who you talk to.
He didn't act like I would have to pay anything, but I guess we'll see. If nothing else, at least I'll save on shipping it.
