Tony I have the Taipan Veteran .25, I was doing a shot string after filling to 250 bar and on the 12th shot I felt a puff of air in my face, not sure what happened, checked the barrel no pellet, tried shooting another pellet same result. The pressure was down to about 170 bar. Tried finding schematic and parts listing; found only the mutant .22 schematic and no parts listing. Can you help me with this? First HP air gun little experience.
