Could you fire lap it?I have a .270 barrel I got off a forum and was going to use. I think, judging from the bore pics that it is toast. Pics are after 4 hours of cleaning and an overnite soaking (filled the barrel w/solution) with Wipeout/Patchout. Not concerned about the remaining copper as that's just more work. The remainder is my concern. Is it fire cracking, corrosion? And the perpendicular rings? New to me!
So, what say you, my more experienced technicians? What do you see? Thanks for your reconnaissance.
