I finally got my Chrony set up and checked the vel on my Discovery.
It is bone stock except for a mellon adjuster. My question is, what should I be getting
for top fps with a 2000psi air fill?? With my adjuster 1/4 turn from spring bind,I am getting 650, 630fps.
I would have thought it would be better. Any suggestions??
