Spinj, if your theory is true, then it should apply to all airguns, not just the Condor. Look at the olympic 10m rifles and pistols. Big difference in barrel length, small difference in velocity, same tac driving accuracy.
Not trying to take anything away from people that want to distill everything down to a mathematical model but changing bore size as part of barrel harmonics ??? I enjoy shooting because it’s both science and art, particularly the art part because I don’t have to understand all the nitty gritty of everything. 😉
On the other hand, anyone wanna trade a 12 inch. .22 barrel for a 24 inch. one ?
