RE: Do you believe a barrel can wear out?
do I believe it "Yes"
I had a T/C hawken I got about 26 years ago. I started to have a problem with groups. I did everything I knew to do and still didn't cure the problem.so I took it to a gun smith.he told me the riffilings were gone.
So I sent it to T/C and they told me the same thing.
They sent me a brand new gun....so yes I do believ you can wear one out.
