PSI Increase

[Lycan]

I think I asked this is another of my post, and excuse me if I seem to ask stupid questions (Still a noob, but learning fast). I set my PSI to 260 because I am still breaking it in. When I was a t Boston Paintball I noticed that after every round the PSI seem to be creaping up morre and more. Now the gun is at 290psi. Is there a reason for this? Any help is much appreiciated!:D

wel i think its jus coz the reg isnt broken but i may be wrong. Wen i first shot mine it did that a bit but after a while it went back down so[shrugs his shoulders]. if it gets too high then just turn it down a bit till ur back at ur current psi
