Don, I hope you are not firing 3" shells in this gun. It is very dangerous as the chambers have been lengthened and possibly the forcing cones also. I would definitely have the barrels wall thickness measured in this area before shooting it again. The chamber pressures are higher in a 20 gauge than in a 12 and 3" is way over the maximum for this gun.
