I don´t have fancy machines to make perfect bullets, but I also managed to get some decent ones too
5mm Carbon steel core with a very sharp point, nylon body, 14mm

Updates:
Support with shock absorber plus adjustable shooting angle 8)
The absorber uses compressed air, so I can also adjust the softness by changing the pressured air that´s inside it, higher mix -> higher pressure used in the shock absorber.
Sadly, I have some important test for now, so shots probably will only come in May
but I have big plans for summer

Thanks Petitlu, yap I though a shock absorber would be cool on a hybrid, as even some big bore pneumatics have one, so for a hybrid it should be a must.

I hope it's well secured to that piston, what mixes are you planning on going to?

I have faith in the connection, as I hammered it several times and it's still solid. After drinking a couple of canned ice tea, I got plenty burst discs, so mix 10 to begin with but I would like to shot it at mix 20.
One question: my barrel is 1/2, so I should use a 3/4 union for burst disc or 1/2 is enough?

I would be
slightly cautious. It looks great I have to say, but there will be a lot of recoil force at 20x and its quite a heavy chamber. I would definitely make sure the tripod was not firmly fixed to the ground, at least for your first shots

I'll take the 3/4!

By using a larger union, you're not gaining any performance and at the same time you have to use bigger burst disks and more layers of whatever you're using, the smaller one is more practical especially if you plan on shooting frequently.

but the flow is lower with smaller discs ..

The important thing is that the flow is equal to your barrel, because no matter how wide the disk is the flow will still be restricted by the barrel size.

Yes!
a fitting 1/2 has an internal diameter of 12mm and with the fitting of 3/4, I can put a 20mm disc inside to keep my flow 12mm ...
