This week I have been revisiting my ss and playing with getting it to shoot 25 grain at about 900-925 fps . I feel I have it where I want it now but in the process of doing it I had to take a lot of shots and I'm noticing my ears are ringing. The gun isn't very loud at all but I think when the hammer slaps the tank it makes a strange ping noise....has this bothered any of you in the hearing dept???
