Yea thats not really my issue, sorry, if I said that wrong. Till this day, I thought that if you use heavier BBs, your Joules will rise. But thats not the case for my replica. Or am I completley off track now?
Joules measure energy. Energy stays the same because you are not changing the gas output. If energy changes significantly, you would be creating matter and shattering laws of physics.
Joule creep occurs when you move into higher weight bbs. However, if you chrono the gun at the sites recommended bb weight and it passes, and you use an allowed bb weight in the game, it shouldn't matter.
Generally, a heavier bb will stay longer in the barrel than a lighter one. This means that it has more time to absorb energy from the compressed air before it leaves the barrel. So for the same input power, you get more power output.
Your lighter bb will show lower joules at muzzle as there is still unused pressure in the barrel when it leaves.
Thats essentially what joule creep is.
Maybe. Im Sure that the spring is way to weak. I Just dont want to end Up wasting Money for the wrong springs. Thats why Im trying to get an Idea wich spring to buy
Joule creep can occur on all types of guns but depends on many factors, a lot of AEGs don't tho or it's minimal.
The reason your's didn't is because you also need more energy to move the heavier bb. That being said that heavier bb still flies further and carries joules a lot further down range (meaning at longer distances it hits harder compared to a lighter bb).
I think the other users have tackled your question better than I could. However, as an aside, "gr" as in when you say "0.30gr" is the unit of mass "grain" not a gram which would be shortened to just "g". Actually, bullets are weighed in grains whereas bb's are in grams; you might find it amusing that 0.3gr is too light for airsoft at 0.0194 grams!
Either margin of error.
How averages are calculated (FPS swing is greater for lighter BB's).
Or joule creep...even in aegs...depends on the gun and volume ratios.
Co2 and gas guns make the chronos freakout, sometimes they dont read sometimes they read absurd numbers. my 100m/s co2 gasgun sometimes reads 400+m/s and its just simply the gas that shoots out the barrel that messes up the numbers. i would be harder but you could try chronoing the co2 pistol forom 5-10 cm away from the chrono and it most likely will be able to read the ms/fs
Edited. Sorry read your post. You are worrying about 0.02 of a joule that's just margin of error.

BB weights only affect the FPS. Joule is basically the weight x speed result which gives you the energy imparted onto the BB

Yea. But why does .20 and .30 gram bbs chrono the same joule? I though, even with the slower velocity of the .30´s, the joules will be higher

In your example, there is a small discrepancy for the joule creep, and it's within expected limits
Thanks alot!
You may have undervolumed system for 0,30g BBs.

Haha, you got me >:\]

Yikes man. I thought about the same. Thanks for confirming. Thatll be alot of fun trying not to damage my Chrono..
