Anyone knows how much FPE does a Hatsan Bully 9mm produce if tuned down for 25-30 shot count

For the sake of no one replying back to this I will, by saying you should invest in a chronograph. No ones going to be able to tell you that unless they physically retune their gun to what you’re looking for, and take the time to set out their chronograph and use up their Ammo.
And even if someone were willing to do that, one man’s tune won’t match up exactly with what your gun will do. If both of you each turned 3.75 turns CCW on the hammer adjustment both will shoot differently still.
On my 30 cal bully I had to drop it down to 885 FPS not only for an increase in shot count(only 5 added shots), but more so for better accuracy.

I didnt ask for anyone to do this for me... Hatsan Bully is a very popular airgun and maybe someone in here has done something similar to what I said. What I asked is if anyone has tune it to 25 shots per fill and the fpe at that shotcount. I know that every airgun has different factory settings but this have nothing to do with what I asked

Fair enough.
I know you’re asking in regards to a 35 cal, but just to give you an idea, 16 shots was the advertised shot count from Hatsan on an out of the box 30 cal starting velocity of 1075 FPS.
After the 3rd shot it started the cliff dive (really bad cliff dive)with each and every shot.
So at 885-888 speeds my shot count went up to like 22, from a 3200 psi fill, but the change was much less of a cliff dive shot string. I suppose if I wanted to get to 25-30 shots my velocity would have to be at around 845 FPS. 44.75g pellet
