What do you mean more air goes "back" into the bolt?
When the bolt goes forward the pillow hits the ball and pushes it forward, and the air goes around the sides of the pillow. So the face of the bolt probably does not even touch the ball unless the lpr is turned up super high and the bolt is moving really fast. If you took the bolt out and held it upright and set a ball on the pillow you would see what I am talking about.
None of this discussion we are having on here explains why the ego is so loud though. Any body got a clue what makes them so loud? Not what makes other guns quiter.
