Nomercy,

Then the real question is this...does the magnus effect due to a strong crosswind coming from the correct direction create enough lifting force to balance or overcome the force of gravity, under REALISTIC shooting conditions?

If it does, then a bullet could in fact experience enough body lift to actually climb above the plane of the barrel. If not, one could say that the force simply acts to retard the decent of the projective by cancelling out some of the accelleration created by gravity (like a parachute).
