I have chronographed my 200S with cencerning results. A few shots with Ultratechs clock close together at between 798 and 805fps with about 2 to 3 out of ten flyers deviating by up to 60fps. This does not seem right. Anyone with suggestions?
Gudio is on the right path. What often happens is that the striker pin spring collapses. You could also check that the striker cocking bolt is not loose. That will cause the striker to drag and also give erratic velocities.
