I have been involved in a discussion concerning the behavior of a bullet during flight. It seems there are long distance shooters who expirence a better MOA at 300+ yards than at 100 yards. The theory pit forth is that when a bullet leaves the muzzle, it is not stable in its flight. This lack of stability causes the bullet to fly in a helix type pattern. This helix occurs around the "true" trajectory. Over time, as the initial velocity decreases the bullet settles in to a proper spin, or what these distance shooters refer to as "goes to sleep". Is this possible? If so, where might I find some scientific articles, or other types of research I may be able to read? Thanks in advance for your response.
