^ Rats. That first dimple explanation got me hopeful.
I remember reading in a book on the history of gunpowder that someone discovered that round balls out of a smoothbore were more accurate when the barrel was bent slightly. Thus, the ball could take a consistent sideways spin (as opposed to the axial spin imparted by spiral rifling) as it exited the barrel. (Book's not readily accessible right now, so I can't cite pages.)
So I have been toying with the idea of taking one of my airsofts and bending the barrel slightly in a vertical direction to increase accuracy.
But I haven't decided on whether I should bend it up or down.
Assuming by "backspin," you mean that the golf ball spins forward on the bottom and backward on the top, I guess if I were to try it, I should bend the barrel downward for a slight increase in range and increasing the accuracy --assuming the sights are re-set appropriately.
What say you?
