Tonight is the first time that I have noticed this thread, but not the first time I have been in a discussion on this topic, what rost495 and Blaine are talking about really does exist. I have seen it several times myself.
I have never heard it refered to as "gyroscopic precession". I have always known or refered to it as "Yaw" or more specificaly "the yaw of repose".
I am not going to get in a debate with non-believers on this topic, if you dont believe go and buy a very fine book by Robert Rinker called "Understanding firearm ballistics". Robert has a chapter in this book that explains this topic very well.
