Hi, I have a Question, no, more of a thought, what is better an opened tail projectile Vs. closed tail projectile after using them both with my crapy leftover (not leftovers from a gun, leftovers from my home plumbing) gun:

My conclusions was that the opened tail Projectile is better,wich is also by my common sense... here is a draw i made to explain what i'm talking about:

Did the closed tail projectile tumble during flight?

I say whatever builds up the most pressure before shooting.

If made uniformly a projectile with a hollow base should fly a lot straighter than a solid one. It is also lighter which means more velocity.
Think of the shape of airgun pellets. Make sure that the center of gravity is well towards the front of the round.

The reason i ask if it tumbled is the plug in the back of the projectile. It looks heavyer then the nose cone. Makes me think it's gonna go end over end inflight.
