Dittos on Rabbit and Robbit's suggestions as to actual cleaning of SxS or singles. I clean all my shotgun barrels like Jack described and clamp the underlugs in a regular bench vice. For padding, I have two pieces of aluminum angle, with adhesive magnetic strips inside the top angle. This holds the angles to the vise jaws. Clamp the under lug between them and drill away. For barrels without flat underlugs, I have two wooden pads with half-round grooves. This will hold a single repeater barrel or SxS barrels. On SxS barrels I feel better about clamping them by the under lugs. Very slight worry that clamping them the other way could flex them enough to loosen solder. Not likely, but I feel better using the lugs. As to the Tipton type moving around, mine is usually clamped in a Black & Decker Work-mate.
