[Strike]

I know what you mean about that motion effect and I agree, I suppose that because bullets fired from a rifled barrel will rotate it could sling some of that phosphor around in circles too, causing that effect. But Generally they look like small worms, from behind they're pretty much just dots travelling up and then down, but from the side they take on a longer shape.. At least how I saw it it looked like they do in IL-2, only much smaller (narrow) and less drop shaped... and perhaps a bit longer.

I'd love to see them bounce off the ground, but this would have to be merged with the ground hit effect, because the game simply hasn't been coded to show ricochets (except from on some planes like the IL-2 where it's a special unique effect)
