my a/a510 was shooting spot on, then used it yesterday morning and after a fill it shoots ok but as the fill pressure dropped so did the poi change, it dropped down and right??,weird as it was still showing about 140-150 bar.then one of the guys at the club said yeah I had that it was the pressure drop in the tube pulling the barrel over as it went down
undo the barrel band and float the barrel see if it helps. ok I went to undo the 2 screws first one rock tight, the second was loose,mmm thought I,so with it loose moved the barrel around let it settle and tightened up both the screws.
what a difference shot the same all the way down the pressure range, so even with a tight screw it still moved needed both tight to make it work. Maybe help someone else one day with the same problem. happy days big smile and spot on target.
