I know with PCP's that with the same set up on the valve (power plant) that a .22 would put out more ft/lb's than a .177, but would this be the same with a springer?
At the moment i'm fixing up a Webley Hawk Mkll that was sold from new with both .177 and .22 barrels, i just have the .177 barrel with this one. so does any body konw if there would be any difference in power output between the two bores coming off the same power plant, piston stroke, transfer port size, et al?
So far i got her running between 8 and 9 ft/lb depending on the pellet used, and that's using an old used main spring from a Relum. I just replaced the two old plastic piston rings with O rings to a sliding fit and greased her up, and made a PTFE top hat and slip washer giving me a smooth shot with 11 FPS variation.
