finally ran some #'s

[Whatsquirrel]

Finally got to run some #'s on the new at44-w short in .177. The first set  with cphp, but it was an air hog. I got 40 shots from a 200 bar fill down to 75bar, with a high of 1095, low of 908.0. So I did the port plug mod & plugged 3 ports, removed the hammer & tighten the adjustment screw to full c.w., removed the spring spacer & put it back together. This time I filled to 125bar & shot down to 60bar. Got 45 great shots this time. Low of 851.9, high of 911.4, avg 889.6 with cphp. After shot 47 velocity started dropping fast so I just stopped there ended at 60bar with a velocity of 819.5. Easier to post a picture of the numbers. Tell what y'all think. Are these good #'s?

Sorry guys it was a 150bar fill, not 125bar. Got my numbers wrong.

Dis some shooting last night, trying a couple of pellets I had laying around. Filled the gun to 150bar & shot 7 clips down to 60bar.  That's seventy shots from a fill. I'm gonna shoot at 20, 25 & 30yrds today to see what kind of groups I'm getting. I'm pump about the shot count. I just did tune on my syn-Rod & getting 80 shots from 2900 down to 1250psi.

Here's my 15-30yrd shots, I shot both the syn-Rod & at44. Just shot cphp's & cpum's. Results, I need to find got pellet for the at44, it's not to bad but can be better. Especially since my at44 qe in .22 does a ragged hole for 20 shots at 27yrds.
