Thank's for the replies,
I have waited over 5 minutes before and found no problem with the poi at 55 yards so maybe it's a new problem?
It's not under ranging as I have checked with my shooting partners after their shot and also shot some of the targets after the comp.
I will need to simulate comp timing of filling and zero check and then see how many shots I need to fire off before my first target.
If my S400 had a match trigger! I would be thinking about making a Steyr style FT stock for it!
It didn't suffer any of this prima donna stuff.
