I always thought rifling was done on black powder rifles that use round lead balls to increase accuracy.
As far as moving. If the ball is spinning on an axis that is in line with it's trajectory the seams would have the same bite all the way around. Not a physicist either. After farther thought I think the ones that move are not perfect bullet spins, probably off a little giving the seams on one side of the axis more exposure to the front of the ball thus more bite.
Sorry for highjacking the thread.
My DD has a natural bullet spin. Instead of coaching it out of her, we have been working with different grips (positions on the ball) to achieve greater movement.
