interestingly, the rouledge concept works for real shotguns as well...example, have a 12 gauge hammer gun with 32" twist steel barrels. barrels walls a little too thin to shoot light smokeless loads. so, inserted 28" briley 20 gauge tubes. test fired with 7 1/2 field loads, at newspaper at 25 yards. achieved wonderful results! both barrels shot right to point of aim and produced uniformly dense patterns...
wonder how this would work with other gauges and barrel/tube lengths?
