So ive been messing around with the U2 compact (mine is .22) and just wondering what other compact owners are getting FPS and shot count wise out of their guns?
Right now mine is shooting FX 18.13g pellets at about 870fps and I'm getting 34 shots from a 300BAR fill before it comes off reg right at about 130 BAR. Honestly I feel like this is low on the shot count? What are you guys getting from the compact? Is this thing just an air hog pushing 18g pellets around that magic 870 number? I have found the hammer spring adjustment does almost nothing FPS wise. I can turn it out or turn it in 4-7 turns and the FPS doesn't really go up or down at all. I have heard others mention this as well. So its hard to tell where Im at on the tuning because I don't get the typical FPS increase indicators to a plateau with HS adjustment like most other airguns. Seems very reg setting dependent
Here is a shot string I just did for example.

862 -Right at 130 bar on the reg. Starts to really drop off after here with a POI shift.
Its shooting quite accurate at 40 yards and consistency seems OK. Just wish the shot count was a little better but I realize the shot count on the compact with smaller bottle will hinder that. Just wondering if Im wasting air somewhere not really knowing what the HS is doing because I dont get much feedback from moving it.
Right now I have the HS basically flush with the back block of the gun as seen here.
I have a Uragan 1 that will shoot 15gr at 825 and 18gr at 775 but I get about 70 shots per 300 bar fill.
