I just picked up a used set of 28 gauge Briley sub-gauge Companion tubes. They are a bit shorter (about 1/2 inch) than the barrels on my Browning Citori 625. Is that normal?
Also, there is a bit of play between the tubes and the bore of the barrel when the tubes are installed. Any trick that I should know of to shim the tubes, without making them too hard to remove.
