Ok I have a Gamo Hunter 220 and I loaned it to my neighbor for some squirrel control. I am now finding after the fact of course he left it cocked the whole time (2 days). It was/is a stock shooter so do you feel the spring was permanently weakened? If that is the case, I think I am going to send it to Gene and get a tune and a muzzle break! If he is willing to take her? Let me know what ya think! Sorry if I posted this in the wrong place The Shop or Gamo Gate did not know.
