What do we really know about the transonic zone?

[Don McDowell]

Jim I agree, it can take a couple of years to work the kinks out of a rifle. One of the best ways to work those kinks out is hit as many matches with it as possible, plus trigger time at home.

Back to the original thought in this thread, the disturbance that may or may not happen with the sonic wave.
Quite frankly I think that disturbance is mostly rational used to try and figure out why a poor target was turned in at a given distance, and makes it an easy excuse to overlook the simple things we can do something about, IE bullet length/diameter, placement of the rest, and not to mention lack of concentration and fat fingering the trigger, along with a whole list of other things.
