Uhmmm. Its very impressive. I like the style of it.

But there is one flaw.
Barrel isn't rifled.
I think thats why your CO2 cartridge twisted during it's flight

The only way we can stabilize ammo such as c02 cartriges is by using fins.

Real world rifling carves into the bullet, we cannot make precise usefull enough rifling to spin a co2 cartridge.

But since potatoes are soft they are spun by potato gun rifling, and according to burnt lake(sp?) it increses accuracy for potatoes by 50%

Yes i know that a bullet it carved with spin grooves. But with a penumatic gun, will slight rifle grooves in the barrel help with areodynamics?

EDIT: Ahh sorry. Not as a question.
Slight spin grooves WILL spin the projectile and help in areodynamics.
