I have been trying to improve on my o ring design, and along the way have noticed that if I use a very minimal crush on the o ring, ie, the piston falls under its own weight, I can use less spring for the same power, but the bounce increases by a considerable amount, so the friction must be controlling the bounce, the power starts to fluctuate also, so it must be bouncing by varying amounts shot to shot. so it seems a bit of friction may be a good thing.

I wonder if this could be the reason some are experiencing poi shift and others not, ie tight or loose seals. Just a thought
