Grains are inherent to laser beam and there is quite a few means of dealing with it. Generally speaking they introduce some sort of decoherence to smear the grains out.
but in our case when we think of extreme throw, i think that this diffusion is provided by the atmosphere, same effect that causes stars to blink. Plus, the ability of human's eye to see the grains degrades with brightness
