Tuning 100 yard group 15 inch BARREL p12 1100 fps 177 with slugs

I do remember the Artemis P12 can be filled past the 2900psi mark as I have read on the GTA forums. BUT...The big BUT is I don't do it or advise people to do it. IT is fking "PRINTED" 2900psi fill for a reason!!!



The P12 uses the P15 airtube, so the manufacturers claimed. But Please dont fking fill it past 3600psi.



The only Airtube I would fill to 4000psi is the ATI Liberty airtube, because it's printed on the tube for 4250psi fill.

P12 is 310cc with max fill of 2900psi. P15 is 265cc with max fill of 3600psi... Ppl should also consider its chinese aluminium without knowledge of what sort and also the fact chinese are really far away from any decent quality, testing and margings we western ppl are used to combined with the fact of trying to make them as cheap as possible.... Even if that cylinder was tested to 8000psi which I highly doubt they do its not no where near of 15000 to 20000psi strenght it would need to use at 5000psi.
