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.

120psi propane wouldn't burn at all, Rob - too little oxygen.

Response to iirc the compressed pressure of propane is 120psi

If you're old enough to remember cars with carburetors, then you know about "flooding" an engine with gas. Too much fuel (i.e., too "rich" a mixture) will put the fire out.

The same principle applies to all fuels that depend on an external oxidizer - propane too.

So if you tried to mix 120psia (i.e., 8 bar) propane with 14.5psia (i.e., 1 bar) air, you wouldn't get more pressure. You'd get no combustion at all.
