Is it theoretically possible to get a round bullet to rise if shot horizontally provided the bullet ( projectile) is given "under spin"?
How about a round hollow bullet made of some light alloy and dimpled then? But shot from a rifle giving it underspin.
Could it be done?
What does the literature say about backspin for dimpled golf balls? Does it produce lift? Enough lift to just partially retard normal gravitational drop, or enough to actually cause the ball to rise? How can you extend that to your question?
