When a bullet turns into the wind, gyroscopic forces also cause it to point downward with a wind from the left, and upward with a wind from the right -- given that the bbl has a RH twist.
    My observation was that all the tipping bullets seemed to be tipping in the SAME direction, and it seems to be too much to be accounted for by a side wind.  One would expect that a bullet going near the speed of sound would tip about 1 degree with a 10 mph wind.   It looks like I am getting a LOT more tipping than that.
     Franklin Mann made a lot of experiments with tipping bullets, but was not able to account for many of his observations, as the science of aerodynamics was completely unknown at that time.(ca 1900) He does give a scheme for measuring the amount of tipping from examination of the bullet holes. An excellent modern source on bullet behavior is Robert McCoy's "Modern Exterior Ballistics". (1998)

I think I'm going with Boats here. I sure don't know anything, and when I listen to too much I just get bogged down in stuff to wonder about. Just shoot 'em and be done with it. It's much more fun than making a problem out of something that never bothered me before. Carry on gents.

Yes Boats that is the belief that the bullet becomes unstable going subsonic and is susceptible to wind. As ballistics is an interesting part of shooting for me I have read up on it for a while, but I have not seen anything relating velocity, wind speed and degrees of tipping. Seems though there would be too many veritables to put a number on it.
