Stan I am not contending that the back to back bananas give parallel bores. I am contending that curved tubes are part of SxS barrel regulation. Coosa's cheap gun could have been regulated by putting curve (more curve) in the tubes when they being were assembled into barrels at the factory. Coosa put the requisite bend in with a file in the last few inches of those tubes to regulate them properly. Had he been so inclined and had the requisite skills he could have taken the ribs and bulkheads off and put curve (more curve) into the tubes and then reassembled them to get the same result.
