Hi,
I play in Italy, max 1Joule for everyone.
My build has a Psionic Upgrades inner barrel and hop-up, which is considered the best in class here in italy.
Their technology says that the set works best with BB's between 0,30 and 0,4.
However, I think 0,38/0,40 is pretty weight for only 1 joule (correct me if I'm wrong) I was thinking to use bbs between 0,3 and 0,36.
I heard that BLS are the best, but I can't find many resellers in Italy.
The next best are Novritsch, so I was thinking to go for them.
If you have any other good brand (better than Novritsch or BLS), easily accessible in europe please let me know.
However, since I will pay a quite expensive delivery I would like to order just one weight, if there is one which would the "best". Which weight do you recommend for such weak spring? Or I need to try all the BB's between 0,3 and 0,4 and find the best myself?

Thank you.

It depends on your barrel length and cylinder volume.

I have ESC works piston, spring guide and cylinder head.
The cylinder is the stock one of WELL MB03.
My barrel length is 303mm

This thread should help: Cylinder:barrel ratios explained
Keep in mind that the MB03 cylinder is smaller in diameter than the standard vsr10 one.
By them way, how is the aiseal with the upgraded cylinder head?

I tried to check that but I don’t know how to measure my barrel ratio.. Am I stupid?

Air seal is great, I upgraded the cylinder head with one with V shape inside, to have more power.

I would suggest .32g for you.
ESC sells BBs I think, but Novritsch and BLS are proven to be great and may cost less.

oh okay thank you I will look into his site, either I’ll go with Novritsch.
thank you!

You don't have to bother with cylinder to barrel ratio, you are at about the ideal ratio for 1J with any BBs.
That being said, you'll very likely like .32 the best.

Thank you.
I have been looking into this guide Magic Marker's BB Analysis
But all the best "Goldenball, Maruzen, Bastard, BLS" are not available here in italy (and europe). I tried to google them but impossible to find.
I think I must go with Novritsch, but when I compare it to the BBs on that google sheet, they look awful...

At 1 joule I would use either between 0.28-0.30gm. Barrel length of 500mm or there about.

My barrel is 303mm, my customizer said that it is the best for my barrel type and for our 1J

I just calculated my barrel to cylinder ratio.
WELL MB03 cylinder has a diameter of 21.93mm and lenght of 275mm
My inner barrel has a diameter of 6.03mm and lenght of 303mm
The calculator on the post gives me 12:1 ratio.
Is this normal? Also, how do i find the correct BB for that ratio?

Thank you

The others really aren't that much better, you'd barely notice a difference.

The whole cylinder to barrel ratio thing is about giving you the maximum FPS with that BB weight, meaning that you would have a bit less noise and have a lighter spring.
But at only 1 joule, it really doesn't matter as long as your barrel isn't too long.
The two advantages to your setup is that it is more maneuverable, and possibly more accurate depending on who you ask.

Okay, thank you very much. I’ll let you guys know as soon as I receive them.
I ordered 0,32 and 0,36 from Novritsch, to test which is better (the price difference on those 2 are incredible, I hope I find the 0,32 way better ahaha).
