Air Arms Owners Club

Hi Experts,

Just concerned with my .22 S200, so I checked it with Chrony from 200 bar down to 60 bar,
I'm not sure if this result is good for 12 ft/lb or should I adjust the power up? hope you can give your feedback....

Thank you.

Pellet used: Crosman Pointed 14.3 grains

I would say that is just about right FPS for a .22

Remember, if you were to use 16 grain air arms pellets, you will probably get very similar or almost the same FPS readings but because the pellet is heavier, the power in ft lbs is higher, so if your concerned that it's a little lower than you like, try a heavier pellet.

Thanks stoohundred, appreciate your feedback
