Thanks, although I'm still at a loss as to what exactly rifling does for a spherical bullet, since a round ball can't "tumble" the way a pointed bullet can. The aerodynamics would seem to be the same whether a ball is spinning during flight or not.

Is the ball deformed as it travels down the barrel so that it's not perfectly round when it leaves the muzzle? I can see where a spin would be helpful if the bullet isn't perfectly round during flight.
