Why are most barrels right twist?
I am not sure if spin drift and the coriolis effect are worth the worry, but in the northern hemisphere if the coriolis effect is said to cause the bullet to impact right of the target do to the counterclockwise rotation of the earth. And spin drift for a right hand twist can cause the bullet to drift to the
right, if this is true I would think a left twist barrel would be better in the northern hemisphere.
I realize the wind is the real culprit but my question is directed at long range shooting at 1000 yds and more.
