Worried about new Shilen barrel

[Adam Lilja]

Polish it with a Flex-Hone. You probably have multiple burrs right in the throat where the neck meets the rifling. Be careful not to force the hone into the throat to deep though or you can risk damaging things from the hard tip on the hone. The rings near the neck can only come from the bore. The strange patterns near the tip look eerily similar to lands as they seem evenly spaced and almost have a consistent twist to them. All that other crap could be from feed ramps, depending how many times you tried to feed each round. I think I would also run a bronze brush thoroughly through the entire barrel in case its not from the chamber reamer.
