Daystate Please help me with reg adjust for my Renegade HP huma regulated

good evening friends of AGN.
Today I received a Daystate Renegade HP R in .25cal from a forum member, but I saw that the regulator is set to 250bar!! This is confirmed by an AOA service sheet where it says that this is how the regulator was adjusted. Well, it's too much pressure, could you help me so I can disassemble and adjust the huma regulator? thank you !!!
 
Maybe try some heavy slugs first?
I recently bought a Rainson Edge X in .25. Out of the box it was set at 140 bar and pushing pellets at 735 fps. It grouped nice at 20 yds ( sighting in on paper) but at 50 yds I couldn't do better than a 4 inch group. I turned up the reg and the groups shrunk down significantly when it reached 170 bar. I actually figured this gun would need to be over 200 bar for slugs.
Seems like most .25 guns are just the .22 version with a barrel swap. If the .22 version is a lil "anemic" the .25 will be much worse.
Good luck!

Yep I guess that this setting was thinking in use slugs but I believe that this renegade is more usable with pellets and is ok to me, thanks bro anyway
