I have a question or 2.
I am having a problem getting the velocity up past 260 fps no matter what I do.
Do you think that the piston is not opening fully because the spring is too stiff?
Something like if you put too strong of a spring in a cocker valve it does not open all the way?
Or is there something I am missing? Or maybe something with the internal reg?
BTW it does have the new hammer/sear in it. I am running it with a 13ci tank, no reg just the inline one. I am confused any help would be great.
