Looks like you may be slightly hot with .2s

From experience that'll be ~360-370ish on a .20g, of course that depends on their chrono setup vs your chrono. My chrono reads FPS as slightly high so and when I go to my local sites they read about 10fps less, so 350fps for me is 340fps on site.
Not sure who is correct though!

All chrono for velocity should be done using .20g unless you are willing to do the calculations.

There is an FPS calculator called FPScalc (find it one google) which you could use.

I have checked on it and it says you would be running at 357fps on 0.2.

But if you are running 0.25 or 0.20 and your site limit is 350fps your gun is to hot. As all sites limits are stated as using 0.20

i make it 358fps so your guna need a downgrade.

Using .25s even at 320fps gives 1.19 joules energy

It depends, only real way to know is to try. But quite often, the heavier the bb weight, the higher the joule that is kicked out as the bb has more time to accelerate (more time in barrel) thus gets more energy. Fully depends on your setup though, but you MAY be ok with .20s, though I wouldn't bank on it.
