The fact that one canot see what is going on between the ribs ought tro scare the hell out of anyone owning an Over/Under with vents in the side ribs. I have always brushed a drop or two of good gun oil on the seams of my double guns' ribs with a soft toothbrush. Methinks some are making mountains out of mole hills. Another item of interest: rather than dipping your barrels into boiling water, try blowing smoke with a thin plastic tube into the drainage or vent holes in the lower rib while plugging the other if there is more than one (and there usually is) you will quickly see any smoke issuing from any gap in the ribs. Just my 2cents' worth. Chopper
