According to Mike Yardley. ,who I think would know , he used the Webley 400 for all his clay pigeon shooting and all his game shooting. I have never heard mention of a separate open choked set of barrels and if this was the case they surely would have been mentioned at some point in the discussion of his successes , perhaps you have a source of such information to back up your conclusion.
