The top analogy sounds great. Except that the top never stabilizes in the same location/orientation because there are too many variables. Likewise, the bullet won't stabilize downrange such that it corrects for error that was previously induced.
Why would a bullet that wobbles and yaws begin to home in on a given point of impact as it travels farther down range like a laser guided bomb?
I beleive that those claiming to have observed this phenomenon have not proven it statistically and/or have not accurately accounted for why they shoot better at long range.
I haven't read the McCoy book. But, I suspect it's being over-stated and/or taken out of context.
Hopefully, Bryan Litz or someone knowledgeable will jump in.
