I don't have a chronograph unfortunately. Could someone suggest what FPS I should use when trying to dial in my scope on Chairgun Pro?
Thank you,
Tom

Chairgun Pro and FX Indy question please
- Thread starter thornstein
- Start date
Duh, sorry, I should have known to post that. High power setting, .22 cal, and usually about 170 to 180 pressure. Using a JBS Jumbo Heavy pellet, 18.13 grams

Don't worry, not rude. What do you mean "if you had a chairgun"? That shot went right over my head.

Maybe linsfreak meant a chrony? I'd suggest that too.
Anyway, on MY .22 Indy at power setting 3:
I pump to around 172 bar, and get 3 consistent shots with (< 10fps ES) at around 885fps with 18.13 JSBs
At same pressure, 15.98 JSBs yield 3 consistent shots (<10 fps ES) at around 935fps
Power setting 2 (which I use for backyard squirrel control)
I pump to around 192 bar and get 6 consistent shots (< 10fps ES) at around 660 fps with JSB 18.13s
At same pressure, 15.98 JSBs yield 6 consistent shots at around 690fps
And 13.4 JSBs yield 6 consistent shots at 735fps
Looks like you are not interested in power level 1 - so I'll skip it.
NOTE: Your result can and likely will be different, hence a suggestion to get a chrony to find the sweet spot.

"thornstein" What do you mean "if you had a chairgun"? That shot went right over my head.
I think what linsfreak was trying to say is you should just look into a chronograph not chairgun. Chronographs are not that expensive and each gun will shoot a little different, so to maximize your airgunning experience it's kind of a must have. I mean if your going to spend that much on a gun why not invest in the gear you will need as well. If you can't afford one right away just put on list of future purchases. Hopefully in the mean time someone can give you some data to get you in the ballpark. Good luck
Thanks Greg you beat me to it.
