Go back and re-install everything. That sounds like where your problem is lying.ripperkon said:Because of the HPA System the FPS (~430fps) are the same.
But in my Test the 6.03 by MadBull was more accurate on long range.
But this weekend I will go out and shoot again with the 6.03 by MadBull. When I can still hit at 70m I am sure the 6.03 465mm by Madbull is more Accurate than the 6.05 470mm by PDI.
Maybe the "theory" with the bigger diameter does only work on lower fps?
