5. The nonlinear Magnus moment acting on caliber .22 match bullets at transonic and subsonic speeds causes a slow-arm limit cycle yaw of approximately 1.8 degrees. The slow arm grows to the limit cycle value at about 50 metres range, and the limit cycle persists out to 100 metres range. The limit cycle yaw adds approximately 2 percent to the zero-yaw drag, but has an insignificant effect on accuracy, retained velocity and wind sensitivity.

"...but has an insignificant effect on accuracy..."

That's the key word. I does effect accuracy, but is it insignificant for 40 yd rabbit hunting, or for 200 yd target shooting?
