Ok, I did shoot gun over Chrony using JSB 18.1's and Power was 825 FPS, trigger pull was dam near 3 pounds, the enclosed test sheet from AoA indicated 875 fps so I dont know what's up with that ? I removed action from stock, found main trigger pull weight adjustment screw and was able to reduce pull down to 1 pound reliably, anything less than that the gun would not cock. I could change out some springs in trigger group but I am ok with one pound with no creep, breaks clean. The gun with factory moderator has a pretty good pop and the DonnyFL Tatsu really quieted gun down substantially. Next I took note of the Regulator setting, was 140 bar from the factory, there is a access hole on bottom of stock to brass screw that lets you adjust the Huma regulator. There is also a hammer tension adjuster at rear of action with a screwdriver slot, I turned in one full turn and power came right up to 870 fps with same 18.1 JSB pellet. I noticed that the adjuster was almost at forward limit before running out of threads so at work today I will make some spacers out of Delrin on the lathe to give me more adjustment if needed..I was able to shoot a quick group and was getting too many flyers so I cleaned barrel and boy was it filthy ! At this point I ran out of daylight, so tonight I will set power where gun shoots best and check accuracy again and do a shot string. I'll try to do this later today. I noticed bolt is a little stiff and hopefully will break in after a few tins of pellets go through gun. Any questions feel free to ask, I have a Crown .25, Regal and a Rapid MFR as well and this gun is a little different.
nd finally got my hands on gun today.
