That's a lot of shots for an Ultra. I imagine if you had recorded the velocity of all those shots over a chrono you would have seen a big drop off in performance towards the end. I recently did a .22 Ultra SE shot string and it gave 40 perfect shots from 220 bar but was going down in power when the pressure was down to 125 bar. The amount of shots you got might suggest your power is also low. it is not unusual for them to come from the factory giving only 10.5 ft/lb, this would use much less air giving more shots.
HFT, for people with only 2 buttucks!
