I don't know anything about cockers, but I did see a thread recently that may be useful:

I think that the gist of it is that there are some tolerance issues and that certain bolts may or may not fit certain breech sizes very well (at least from a blowback perspective). If this isn't the particular issue you are seeing, it may at least be informative and it will show you the names of people who definitely have cockers that you might want to PM.
