I know that ChuckH did it himself several years ago, and documented the results on this forum, with photographs and a detailed description of the process. But, these bores are chrome lined and I wouldn't get much done in them using the process Chuck used, I'm afraid. I also want Orlen to lengthen the cones in it. Chuck also documented a huge improvement in patterns with the .410 by doing that. Orlen already told me that chrome lined bores are not a problem for him.
