[QUOTE="Michael Eichele, post: 355166, member: 1007"] Gonna need the bullet's overall length and a twist rate as well as direction of twist for accurate spin drift numbers. ;) Also, you say the wind is 5 MPH at 90 degrees. Which 90 degrees? Wind from 3:00 or from 9:00? This WILL make a difference with its relation to spin drift and the coriolus effect. At least for my personal calculators. [/QUOTE]
