I bouhgt this 2nd hand Hatsan mod70 for a great prize, and considered the whole downtuning mission. Already added the muttoncloth to the stock helping a lot with the sound issue. But now i have other concerns. The Hatsan is supposed to be around 1000fps , but shooting it through the chrono i found an avarage of 780fps , needless to say this comes with a heck of a recoil and some good noice. Now the question is, if i do the downtuning for accuracy and less recoil, how wil this affect the speed. Is this standard speed or could there be something wrong?
