Scot Laughlin's Custom All Weather 2260

2260 with short crosman receiver atop a mini riser made from aluminum tube. Barrel is a 2200 soda straw
tensioned inside a titanium golf club shaft. Three screw mod to the trigger, bulk co2, SSP 250 rear cocking
striker assembly. Factory stock, reshaped, bedliner finish and stick on cheek piece. The idea was a weather
resistant light hunter for rainy days.
I've got a Cothran stainless receiver and gas tube waiting for me to get back to this one.

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?
