Our squirrel season is over on Saturday. So I am already thinking about next year. I am not having any issues with the gun or anything but I suspect that my Yong Heng Pump has been allowing moisture into my gun. (I have not changed the filters on the pump like I should and I noticed the fill probe has corrosion on the end that attaches to the hose). I was thinking about replacing the seals and have it checked for moisture problems. I am going to get a different pump and possibly hand pump during the hunting season just to top the gun back off. The gun shoots great and I have it tuned exactly like it. This is exclusively a hunting gun and I don't shoot it that much outside the season. I just want to make sure its okay and there are not any issues before next hunting season. Is there someone you guys could recommend that I could send my gun to that would change the seals and check it for any moisture damage? Thanks for the help!
