Brock, be nice. There's no need to flame the guy for showing us something cool.
Cetane, ceramic ball bearings are pretty much indestructible. When a ceramic bearing fails, it's because the ceramic balls have dented the steel races. The bearing explodes and the balls are still perfectly round. I'm curious to know how similar in performance to silica BBs those would be.
Also as I had mentioned before, the idea of rifled shuttlecock rounds does not work nearly as well in theory as hopup does on a spheroid. And it HAS been done in practice, and performs even worse.
The reason for this is because the projectiles are so light, any spin on them is very prone to
the magnus effect. So whereas backspin (hopup) on a BB will cause it to lift up into the air, rifling will cause it to veer off sharply in a given direction.
Non rifled shuttlecock rounds will fly more accurately than non spinning spheroids, but they won't go as far due to the increased drag.
Backspin stabilizes the spheroid and allows it to physically lift up through the air, producing a very accurate and flat trajectory over very long distances.
I want you to think really hard about just how small a 6mm BB is, and just how light .30g is, and then understand just how significant it is for that tiny lightweight projectile to fly 260 to 300ft at a muzzle energy of only 1.6 joules and have someone notice the impact.
