In case anyone wants to know why spinning (round) bullets are more accurate, it’s because any deviation or wobble in the bullet will alter the flight path (wind resistance being a thing). By spinning the bullet, it averages out the deviations in all directions - so to speak. Any wobbles will stabilize as well.
Yes. Square bullets would catch the wind and fly in unpredictable directions.
They spiral the barrels of guns to get the bullets spinning and more accurate.
