if we were to use a spring loaded cylinder we would use the 2" bore with a 4" stroke and a front spring bias. this accomplishes the extra force needed and the extra velocity. the spring described in this system has 30 lbs. force by itself. with the pneumatics added this will be increased more. btw this is offered by clippard
