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.

With stock valve stem, stock weight valve spring, and stock weight hammer spring. Valve has no porting or polishing. The breech is Cothran Machine with hollow bolt. Gun has a 12 inch barrel. Velocity Adjuster was unscrewed all the way, so no extra tension on the spring. Also used one of Anthony's Protops to test the gun with 12 gram cartridges.

Temp 65 degrees using co2 12 gram
14.66 grain Beeman FTS domed
CED Millennium Chronograph

I will be testing again tomorrow when it is warmer. I also replaced the stock stem with a polished ground down one. I haven't started porting the valve, and I am over 9 ft/lbs for at least 1 shot.
