Replacement Hatsan flashpup .22 round 2 with DonnyFL Sumo no QE.

Ok so i finally have my replacement in hand after the return of my first flashpup.



Here is the chrono right out of the box with the Suma and no QE oem system.

As you can see. This is from 200 bar to 100 bar. The chart shows 41 shots but my chrono didn't pick up 3 of those shots so they are in the middle from 20-30 so makes the total shots 44 from 200-100 bar.



Looks like the fps are close up till about shot 28. There is a rise at the beginning but not a terrible lot.



If my math is right and shooting from 200 bar (2900psi) down to 100 bar (1450psi) it requires right about 2.25 bar (33psi) per shot. This is of course based off the 44 shots not the 41 in the chart. 



So my question is should i leave it shooting fast like it is or back it off to aroun 850-875 range and go from there. Bottom of this i have attracched 2 seperate images for a prior date of the hatsan i sent back shooting around 850is and i was able to get 80 shots from 200-100 bar and i think more usuable shots. This all both coming from 14.3 gr crossman hollow points. As this is all i have access to currently.
