Subject: Re: Buoyant Bullets
It is a common-place of ballistics that a well-spun shell by holding
its attitude near to its initial elevation develops lift as it drops.
It is also well known that the general run of say - pistol bullets nutate
markedly about their flight axis and do not develop lift in the same way.
John did NOT report lift due to a horizontal drag force (or if he did,
he doubtless regrets it.) I recall he mentioned there must be at least a
small vertical component.
