So will a fast semi show signs of shootdown thru a tight barrel with long dwell? i.e the second ball stealing air flow/pressure from the first ball still in the barrel and then possibly the friction on the first round as it gets to the end of the barrel with less pressure?
prolly a dumb question, but....
