EdGun specialist Ted of "Teds holdover" did a vid re pellet speed v stability a while back - which was interesting, some good slow mo stuff.
I think he was proving that fast was not always best - if I remember right. But as he shoots FAC mostly then maybe not directly relevant.
Like everything in this sport, there seems to be effective combinations and non effective ones, there in lies the beauty of it all I feel.
