Dag Evert's "American Classic"

As mentioned on the forum, heres a picture I took some time back, with natural winter daylight.
A 2100, and a 1377, both guns have been recrowned, and had their trigger parts shimmed for play,
contact surfaces stoned, and trigger springs somewhat reduced within safe limits.
The 2100 has had its barrel shimmed with tape to remove play.
Both guns give great accuracy for the money if they are given good pellets!
The combination of pellets and guns in the picture represents something close to my boyhood dreams:-)

Yes. I agree, James. But whether the piston moves or not...

Response to If the gun shoots faster with,

...during the firing cycle, there must have been a significant fraction of the total volume of the air charge between the piston crown and the port before the valve opened.

So, whether the piston moves or not, the effect would be the same. If the port is so restrictive as to interfere with that fraction of the charge doing its share to pressurize the bore and push the pellet, velocity will suffer. No?
