I just did a little back checking on my past posts regarding my .22 Airmax pistol.
I had chrony tests of it shooting in the 560 fps range. What I can't remember
is if that was after I slowed it down for more shot count. I originally thought
it was closer to 600 fps. I would have been shooting JSB 15.89. The gun was
accurate and a great shorter range pester. Trigger mod videos out there too.
