Back Room / Penetrating 3/4" plywood with a pingpong ball

With such a low BC projectile, is this pingpong ball shooter
the ultimate short range urban pesting airgun?   
(never mind portability, and few other limiting factors  :) :)  )

We had been watching the series Gunsmoke on one channel, much to our surprise we hit a couple episodes that we had seen before; and they cut out some pretty important scenes to make more room for commercials  >:(
Jeeeeeeeeeeeeeeeeeeeeeeeezzzzzzzzzzzz.......
Heck, not once have I EVER clicked/called/whatever on whatever service/product that was being advertised... Talk about a waste of money  ::) :P

 Trick is to have your buddies in their stands, then drive around in the trucks with bagpipe music or the other evil equivalents , to drive the deer, at mid day they switch places for mental health reasons :)  ::)

Allan,

The energy and mass of air in the pressurized region behind the projectile is capable of much more projectile buffeting than the barrel full of air in front of it.

Yes, some air or propellant gas leaks past the projectile, but that is a fraction of what is pushing behind it.  So, that raises the pressure a little.  As does the bullet shoving the air out of the way.

So, for metal projectiles, air or gas ahead of the projectile is observed, but ignored.  An air stripper fitted to redirect blast that follow the projectile, can and will scrub off some air that leads the projectile - but that is incidental.

Your statement is absolutely correct, when using a "vacuum cannon" to shoot pingpong balls at supersonic velocities.   There an air stripper ahead of the muzzle can absorb the air that leaks past the ball to very useful effect - making it easier to get the ball moving really fast.

The "air stripper/ accumulator" is shown at the top banner of this youtube channel about shooting ping pong balls supersonic:

EDIT:  Found a video showing such an airstripper / accumulator working on a vacuum cannon, here:
