Shuriken Weaponry: Self-Feeding Ammo Mag

So, I don't know if this is something everyone knows, so sorry for geeking out, but I didn't actually know that the ammo for shuriken catapults works this way

The ammunition for a shuriken weapon is a solid core made of plastic-crystal material. High-energy blasts are created at the back of the weapon and push the ammo through the barrel at incredible speed. Each blast slices off a tiny piece of the ammo and shoots it out of the barrel at speeds faster than sound, making it deadly to most soldiers

The ammo magazine itself is made of a solid plastic-crystal core. As it's fired, it feeds into the weapon, being turned into tiny, high-speed slices by powerful energy blasts, causing the mag to shrink as it's fed in. This is really cool, such a unique ammo concept for an Aeldari weapon.
