Worried about new Shilen barrel

[LRRPF52]

Here's a video on youtube that shows one way of approaching it. I preface this as I mentioned above, by plugging the chamber with foam to prevent any unwanted and potentially chamber-damaging compound from getting in there. I also take the polishing head over the edges of the feed ramps to "melt down" the sharp surfaces, and those of us with the Lilja barrels can see that has been done by the tumble polish already.
