Anyone else testing/tested via Chronograph the speeds?

[Intercooler]

    Of the factory ammo I have done on the sheet? I don't know anymore if my numbers are off, valid, etc...  I want to do PBR again now that the Match is up and I have my Chrony rebuilt. Post up if you saw a big difference up or down from what I got.


I have this new BB Gun that does 600-650 FPS and I'm wondering if I should use it for a control rather than the .22LR (1000-1100 FPS) I usually use?
