Tuning Efficiency of my upgraded RAW HM1000X .22

[mubhaur]

Starting air pressure 245 bars

Ending air pressure 145 bars

Air consumed 100 bars

Pellets used 18.13 grain 

Average speed 959 fps

Total shots achieved 140

Energy per shot 37.015 ftlb

Extreme spread in 140 shots 15 fps

Efficiency = (air consumed in bars x bottle capacity)÷ (number of shots achieved x energy in ftlb)

Efficiency in my case is 9.26 bar. Cc / fpe

This is the final result of the complete upgradation of my RAW HM1000X .22

1.77 avg FPE / cu-in per shot is outstanding efficiency. Great job! I’m assuming you have a 480cc bottle? Your ES for a 140 shot string is also as good as it gets. Nice!

Nice video and great work on your RAW.

My HM1000 .22 HP shoots very accurately at 50-100 yards with the JSB 25.39 RDs at around 940-945 FPS. Better at 50 though. 

The 18’s fly too fast in my stock configuration ( no mods). 



Enjoy reading your posts about the RAW.

Sorry I could not reply quickly as there was some issues with Internet connection. 

Yes my bottle is 480cc

Thanks Tom

I get better 100 yards accuracy with .22 redesigned 25 grain pellets at around 950 to 970 fps in my RAW
