Is there any point in shooting soup out the barrel of your gun? We're talking about swapping to the smoothbore barrel in order to eliminate a possible cause of your problem. If it doesn't fix the problem, you can move on to looking for something else. If it DOES fix the problem, then you can shoot smoothbore until you find another solution.
UV Halo has made extensive posts about the Lapco barrel being too tight and fouling up after about 60-80 rounds. His solution was to use a rubber squeegee to remove the fouling.
