I think your experiment shows the air in the headspace contributes to power

Response to Hi Walter, the piston extending after the shot (does) add power,

but inconclusive WRT flex of the system adding power.
In that 2004 the change in piston length will likely be in the order of 0.010" so doubt it is the source of power you lost.
Cool example of the idea if your idea is correct though happy.gif

Walter....
