[QUOTE="Brown Dog, post: 177529, member: 1622"] AJ, Another quote from your link (well, the page preceding the one linked) "In other words, the maximum yaw angle, which occurs close to the muzzle, is damped out as the bullet moves on. After a traveling distance of a few thousand calibers, depending on the damping rate, the transient yaw angle practically approaches zero." If you're happy with the concept described (of bullets being rather unstable at launch, but stabilising as they get further downrange).......Simply apply it to the apparent yaw angle produced by the trajectory falling away from the bullet....all that's happening is that that yaw is being gyroscopically damped out to match the changing airflow....in just the same way that transient yaw is damped. Hope that makes it a little clearer! [/QUOTE]
