Hi all. I don't have a lot of experience with air guns so I will try and explain this as best as possible. Model is in the title, .177, 495fps.Lead pellets, loads properly, barrel breaks normally. When you fire the gun the pellet only travels about an inch down the tube. Is this a broken spring or a seal issue and is it something I can repair myself? As well, can I increase the power to 600fps and if so, how? I will sit back and read the input. Many thanks.
