Those patterns will kill turkeys but I wouldn't be content with those results at all, especially considering the fact that you have a polished barrel in an earlier post.
Are you sure the person who polished your barrel knew what they were doing?
Are you using a boresnake to clean your barrel between shots?
Are you benched when shooting?
Are you sure that your point of aim is not different from your point of impact and that some of the pattern is not missing the target entirely?
