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.
That would lead me to believe the that at that pressure range, with that valve set up, a transfer port giving something in the 13-16 foot pound range is probably at its optimum. Change some other factor, like the operating pressure or the valve cycle, and would need to retest.
