A while back we had a disscusion of the wide range of actual bore dimensions found on many 12ga guns. I was reading some posts here concerning choke tube installation and am wondering if when a company, such as Briley, installs tubes are they custom made to match the bore of the gun? I would assume this might be the case? If this is done and new or replacement tubes are required later on must one have the custom dimensions for their own gun? Has anyone ever bought choke tubes for a gun and found they didn't fit or really chewed plastic wads up or any other problems? I am thinking specifically of guns with bore diameters larger than standard. Thanks
