Its small bore(.684) which means you can shoot the ball though cracks in the walls! I shot theis guy how has hiding behind a bunker that had a small crack. The ball went straght through and got him in the mask. It was lucky but kewl.
Half of the balls i got were dimpled but the others were fine.
You better make sure you hae a barrel thats at least a .688 bore. These balls are small and you dont want ball rolling out of you barrell
