Have you got access to a downrange chrono? Such as a Pro Chrono?
If you're going to be doing some range testing with/without an airstripper, I'd be really interested in seeing what difference it made to your downrange velocity.
The theory being, that if an airstripper actually does make the pellet more stable in it's early stages of flight by stripping away turbulent air, then that should show with an increase in downrange velocity.
My suspicion is that Holly's right
