Puck "expands" if I pull the PF out of the cylinder. It's actually pushed up by atmospheric pressure, as when pulling it, vacuum forms between the puck and piston
If I push the piston through the cylinder to push the PF out, puck doesn't "expand". I had to do it this way with original PF due to very tight fit (sometimes I even had to use a rubber mallet to hit the piston 1 or 2 times). My bottomless PF doesn't have as tight fit, it's relatively easy to pull it out
