Does anyone know if the inventors of the FS round tried straight fins?
I have a suspicion that spinning the rounds with angled fins does not do much... and that the rounds go straight more because they are like a badminton shuttlecock than a spinning bullet.
Which means that if the fins were straight, the FS round would probably have less drag.
I have also never seen a shuttlecock with angled fins. Yet shuttlecocks don't need to spin to fly straight.
