I’d be happy if my .22 would stay that consistent.

Highest 913
Lowest 890 – discounted first shot as presumed off regulator when recharged .

ES 23
SD 4.69
Accuracy at 50 metres ok some flyers
“. 100 metres seems more accurate at this range , still some flyers, best 5 shot group 1.5 inches.
I am not a good shot!
Thoughts
Looking for more consistency, the ES is poor.
Why the flyers , probably 2 out of every 9 shots?
Should I try filling at say 230 bar and leave HST setting alone. Or reduce HST by 1/4 turn CCW and fill to say 230 bar.
Certainly the hold is all important , the right squeeze necessary.
Scope Edgun 10-44 fixed mag. Very similar to SWFA.
Love the gun though.
OK after the chrony numbers yesterday I did some 70 and 50 yard groups. I managed to consistently do 1/2 mildot size groups. At 50 they were 1/4 mildot size with one flyer. I did manage to do a 3 shot hole in one. The gun was very consistent through all 4 clips on a 230 bar fill. It does seem you have to hold it in the right relaxed way to get it to perform.

looks like you are shooting in the front room, hope the wife was not home!
:rofl: :rofl: :rofl:
Nope this is my work table for my guns. Its not in the house.
I was thinking the same thing. Could it be the regulators are not quite up to snuff
I don’t like that extreme spread. Needs to come down a bit. The reg on this gun should be more consistent then this.
nice numbers, shooting good now.

Mike it’s very similar to what I’m getting although I turned mine back a smidge to keep the 900 plus spikes down. Out of 3 strings this one I posted was the best. Mine does one spike and one lower to screw up the ES. I think the regulators have issues. When turning the hammer spring make sure you only turn it a tiny bit. It’s not like the cricket where you turn 1/4 turn at a time.
