FX Royale 400

I did look at the screw that holds the cocking lever, and it is fine. I even added a little lube, no avail. I'm not sure what to do. My rifle is tuned to shoot 18.1 gr JSB's at 830 fps. It looks like it might be a trigger thing. When I cock the rifle, the trigger is not locking the sear back. This is probobly the problem. 

Tahnks guys for the advice. Much appreciated.

I took the gun apart a few days ago. I stripped everything. The only thing that I saw, was that the sear was not engaging the hammer spring. I had a close look at the sear. It was worn down by quite a big margin. I guess that happens when you have shot your rifle tens of thousands of times.

I have shipped it back to the dealer, they called me this morning to let me know, it only needs a new sear. Now the waiting game begins. They have to get a part from FX. This might take a while. 



Thank you guys very much for all your advice.
