This is complete bunkum based on a total lack of knowledge on the basics of aerodynamic stability. It also fails to explain why a wadcutter pellet is apparently still stable despite the vast majority of its drag being at the front rather than the back of the pellet.
Oh man, your static force picture is way out. First of all the normal force is pointed inward from the arc of flight, and so is gravity, you have one force forward and that is the momentum of the pellet, in tangent of the arc of flight.
Then there is air friction slowing the pellet down force vector pointing straight against from the direction of movement. From your picture I would say the pellet has no mass and it would just float to space. Marko
I made a pair of pictures based to same diameter same length bullet by Kolbe's calculator which I have tested in practic and found to be spot on by few %. We must call this slug because Kolbe does not include pellet form. But anyway there is something interesting for this particular question.First picture is sharp nose blunt base bullet and what interest us the most is subsonic speed....compared to blunt nose boat tail bullet of same size.Remarkable difference in BC and drag. I'm sure you as a ballistic expert can explain this to me.
It has been shown in wind tunnel tests that the axial force does not change in magnitude until large angles of yaw are obtained so any change in drag at low yaw angles is caused by the tiny component of normal force in the drag direction.
do you call it lift if the pellet is at its opposite oscillating position nose pointing downward.
