Vapo, I' m not talking about the winds ability to slow the bullet I' m talking about windage, when a bullet leaves the muzzle it is free floating, if being big and heavy makes a difference then why do jet liners allow for cross winds when in flight. If you had 2 planes, one a commercial jet the other a small lear jet both traveling the same speed, same route in the same wind would the smaller one be blowed off course more than the big one? I still think a 300 grain bullet traveling at 3000 FPS when it hits the target will be affected by the wind as much as a 75grain bullet traveling the same.
