leshiy reg pressure vs barrel lenth and cal

Every single rifle is different so you need to follow Brian’s instructions https://www.edgunwest.com/blog/tuning-the-leshiy

Do you have a Huma reg or the stock reg? My .177 is all stock and I get 26 shots from 240bar down to 120bar (the only shot string I have recorded). This is with Jsb 10.3's at 820fps. I have no idea if this is good or bad but I haven't found a need to change it yet lol. I've never really cared about efficiency as I shoot at home and can always refill my gun.

I have my .25 caliber ser at 108 on the Huma for the long barrel and get 830fps at 10 clicks on the hammer spring. This will get me 16-17 shots and is incredibly accurate. That is with filling to 250 Bar.

Mine is a Huma regulator so has a slightly larger plenum then the stock EDgun unit.
