My Wildcat is averaging 933 fps with JSB 25.39 pellets. I'd like to bring it down to 900 fps. I bought it used, and it appears it has been adjusted before. I say this because the hammer adjustment brass screw was not locked like many have found to be the case. That being said, I turned the screw counterclockwise a half turn with no change in fps. I was concerned about turning it further because the screw became very loose, it was not snug. In fact, if it did lower my fps, I would be concerned that the screw would be too loose and not hold that position. I watched a YouTube video on the disassembly of the gun by Ernest Rowe, and while he did not do a hammer adjustment, he indicated it is tricky, but did not explain any further. Anybody out there who can provide me some help?

Try the JSB 33gr in it. That should drop it and give you a nice whap.
OK, I figured it out. Here is what needs to be done. The brass screw on the back of the receiver is just a cover. Behind it is a black plastic or delrin screw. That it what is used to increase or decrease hammer strike. I turned mine counterclockwise almost 1 full turn, and brought the FPS down to 902 from 930. Attached are a few photos.
