To add a bit more to the rambling , all mechical contraptions humans use are simply dividing the work over time and distance. BE it a long torque wrench or pumping a gun 10 times as opposed to 1. I built a drill powered pump for the 880 at once point , it was literally 2 feet long off the front of the gun and was powered by my cordless drill. fairly slow process, but i guess my point is the human is the limiting factor. Another idea that was cool but not practical was posted on the green 12 yrs aago , It was 2 1377s blended into one wiith a custom breech , linked triggers, everything linked.. Really interesting , im pretty sure the thread is lost in the archives now

Really interesting , im pretty sure the thread is lost in the archives nowFunny thing Rob, I had actually pondered that by using 2 compression tube assemblies side by side and yet only using 1 breech/barrel assembly. Thereby getting 2 times the air per stroke If we could just figure out a way to get a stroke of air on both the upstroke and down stroke at the same time. Then a 10 pump gun would become a 5 pump gun:)I've been looking through pics of HPA air pumps but can't wrap my mind around all those o-rings and check valves yet.But I'm still thinking Thanks Ray

No backstroke neededd. His gun had double volume , SO throwing a 25 cal pellet at decent pistol speed on 10 pumps would be no issue..So theres 2things to look at , pressure X volume.. ANd thus a large swept volume SSP has infinite tuning options.
and that experiement proves why volume is half the battle..your losses in volume outweighed the gain in pressure. with the dual 1377 we discussed, he sacrificed neither, just doubled the volume
The Webley Paradigm will always be my dream gun I remember saving money for that one but it never came out
