At close range spin doesn’t have that much of an effect, but what is the effect of a bullet’s spin at longer distances?
As a bullet leaves the barrell, the spin forced on it due to the rifling causes a drift that if left uncompensated will cause a miss of center and possibly the entire target.
Check out this video on how to compensate and in turn develop better accuracy.
As usual, the guys at Gunwerks explains ballistics in a way that even the novice shooter can understand.
It’s not that you won’t miss again, but maybe you can now know why.
