EDgun EdGun R5M Huma Regulator set point

I am doing a reseal on my R5M in .25 caliber and I am installing a new Huma Hi Powered Regulator in the unit. What would be a good set point for the regulator to push pellets, though also able to work with a decent weight slug?

Well son of a gun ...... I removed the air cylinder only to find that there is already a Huma power regulator in the cylinder! Well crap, so now I either have to worry about keeping this new regulator safe somewhere, or sell it to someone that needs it. Heck it hasn't been out of the bag yet. lol


What do you guys think?

The setting on it currently was 115bar I believe, I upped it up 125 to get a little more power if needed. I can always back down the hammer spring as well if needed.

Now I am looking for a guide on how to redo all the seals in the rifle. Looking on EdGun West right now on the schematic and see all the seals and trying to formulate a plan on how to get to them all.
