Anyone know what is the 575 FPS (5Joules) current air volume of the Fwb 603 SSP ?
And what would it require , hypothetically asking , if one were to make a longer SSP tube out of titanium for an increase to within 11.5 ft/lb ?
Or asked another way, has anyone ever tried successfully got the FPS up ?
