Matthias is correct.....Spheroid ammo is most forgiving. Part of the reason I use it almost exclusively for target sport. Smooth surfaced ball ammo works quite well here.
As for distance slinging, I prefer darts.
I myself, do not have a dedicated interest in engineered ellipsoid ammo, and I would certainly accede to your numbers, Matthias.
(No need to fire up the 'hot air windtunnel' here.
)
Matthias, your general statement regarding points is certainly valid as well. I have borrowed from the archery manufacturing community in my efforts and found that some 'points' provide quite acceptable subsonic performance......particularly those made by Saunders Archery Company.
The drag increase resultant from an increased bow wave diameter is largely mitigated by smaller body diameters and avoiding angularity.
Of course, this is not to say that there are not ways to eke out more distance using creative 'short body' geometry! There is certainly a largely unexplored frontier here.....and exploiting high RPM spin characteristics aerodynamically seems to show promise.
Your 'turbulator' ammo is certainly eye catching......the addition of the 'turbulators' reminds me of one of Nerf's later football efforts! There is also some resemblence to a few 'Boat-tail' bullets I have seen.
I would imagine that perhaps a decent market may be established for production line ammo of such a sort....
