I have a jkhan .22 noblesse I bought several months ago and today is the first day I've had a chance to shoot it. I have a cf tank with a 3000 psi reg to fill with. But at first several tries i t would not fill to 3000 and immediately leaked down to 150 bar. After shooting it a few times and trying to refill its holding but still will not fill to 200 bar. And it seems to be using a lot of air. I'll chrony it tomorrow if I can and check shot count. Any ideas?? Maybe my gun guage is wrong??

Problem seems to have worked itself out. Shot a few quick rounds with three different pellets.
Jsb 18-1038-1034 / 21 coppers-987-983 / Rabbit Magnums- 25-907-903 . Two shots each. 2800 psi ...Korean shot cliff. I'll tune it later but some nice power and accuracy at 40 yards. I will run some longer shot strings with each when I can for more definitive accuracy results.

Thanks Mr. Geoffrey. Finally got some time for this one. It was leaking at the gauge. I removed the stock and checking things as I went and the pressure gauge just turned in my hand. Tightened it back up and its holding air like a champ. I really like this gun! Light weight, shoulders quick, and the perfect length for me. The jkhan has an adjustment on the hammer spring after removing the stock, like the evanix from what I hear, and makes it really nice for a little extra power when needed. The stock prevents it from being let out any further for lower power but I'm going to fix that. I'll indent the stock with a bit and put a small hole in the thumb hold area so I can adjust it with a small flat head driver. Adjustment on the fly! I use this for varmint control and it works well. Needs a few baffles, either mine were missing or they don't come with them.
I put a light with red laser and red filter for those night time marauders, turn my open reticle to green and they show up perfect:)

Finally got back to the noblesse .22 today. The power adjuster is able to turn in 7 full rotations from flush. On flush, I was able to shoot the 25 grain rabbit magnums at 907 peak. However, like the evanix, it is not able to be adjusted out because of the stock. Well, today I fixed that. I routed out the rear of the stock behind the adjuster and the gauge hole, because the action must go in on an angle with the adjuster out. I can adjust out 3 full turns maybe four. I will not know until I get a chance to shoot over the chrony what this will allow me to do with my shot strings, but should allow me to tune for a flatter curve. From the outside there is no evidence of the modification.

Shot string with adjuster 3 1/2 turns in. 25 grain rabbit magnums, 2900 psi. 958,,956,952,948,941,944,943,941,933,929,921
41 fps higher on the peak from the previous 907 fps for 52.53 ft lbs max.
Shot string with adjuster 3 1/2 turns in 18.13 jsb 2900 psi. 1068, 1060,1057,1043,1041, 1031
Shot string with adjuster 3 1/2 turns out. 18.13 jsb 2900 psi 1055,1049,1040,1035,1032,1026
Adjusting out did not make a lot of difference but I think I'm in need of a slightly weaker spring for a flatter string with the ability to adjust up or down. This gun has proven itself to be very accurate with the rabbit magnums, Kodiak 21, and the jsb 18 at 50 yards. With a little spring tuning this will have a great shot count and accuracy. Nice to be able to crank it up for a hunting day or down for plinking.
