I'm 99% certain that the spiralling effect in the tracer smoke is down to rifling of the barrel causing the rounds to spin, rather than any camera-shake effect.

I'm really happy that this effect is modelled (visible on many gun-camera films from this era), but as Oleg has said previously all different types of round are modelled - previous tracers showed simple light-streaks with no smoke. I have no doubt that all are modelled accurately.

I'm a little bit surprised at some of the reactions to the spiral tracer smoke though - when the previous tracers were shown there was a chorus of voices asking where was the smoke?!?

Yes, the spiralling effect in the tracer smoke is because of the rifling of the barrel...absolutely

I really like the little JG 26 Crow. One of my favorite insignias. So whimsical.

I'm sure other factors were at play too as others have recently mentioned. The rifling of the barrel spins the bullet but it takes other factors to exagerate that spin and make it gyrate to the extent we're seeing in the films.

Yes, like these and others no doubt:

I think a combination of both for sure. The flight path of bullets gets very erratic when the mach barrier is crossed as they slow, after only 2 or 3 seconds of flight time. Add the sideways movements of the platform, caused by the firing of guns themselves. Another factor being any sideslip of the aircraft during the firing, introducing strong crosswind on the projectile. These would all combine to give a pronounced image to the viewer. __________________

Whoops Sorry Slipball, yes, those other factors you've already mentioned!

I think the debate was about whether the smaller RAF 303 rounds should have smoking tracers or not. In IL2 they didn't while the larger rounds did.

I've seen plenty of footage of smoke trails coming from 303 rounds but I'm sure as Oleg says, different tracers had different properties and some types may have been smokeless.
