Quote:Spheres, no matter how they orientate, provide a uniform front to the air. That's why I think they're the overall superior and more accurate sling projectile in practice.
And simpler to work with! Though ovoid, bi-conical, and other enlongated variants can be made to fly quite well, employing spin stabilization along the projectile's longitudinal axis. Sling ammo is much larger than rifle ammo, and tends to spin too fast compared to it's forward speed. This can be controlled by pocket shape, size, and orientation. By creating a release system that dramatically lessens pocket contact duration after release, ballistic spin ratios are made more manageable along with vastly increased release consistency and pocket durability.
Though such efforts are admittedly, obssessive.
