A quick video on aerodynamic jump. Its effects and how to compensate. Prequel to a much more in depth wind calls video.

I believe? In a 90deg. L or R wind, there is a low PSI area generated above or below the spinning projectile? (Depending on R twist or L twist rifling) This effect is more pronounced in a standard rifled barrel vs. say a polygonal or smooth twist barrel, also in my mind I think L-wind low, R-wind hi. Not sure about my low psi theory being accurate? Been awhile since my last physics class... but very nicely done well explained and demonstrated!
