Let me ask you a question, Miller. If it's "just a simple tube", as you said, can you explain why barrels made exactly the same, as near as man can make them the same, don't always pattern the same? I can assure you they don't, based on many years of patterning. There are generalities that can be "assumed" when assigning loads to barrel/choke combinations, but there are those individuals that do not follow the "rules". Why?
The easy answer is that they're not really the same, but are different. And, if they really are different, can one make assumptions that a simple tube with a certain bore and constriction will perform a certain way? A "certain way" meaning according to the median for that bore/constriction.
