I'm not arguing, I just have a different opinion.
Personally I think you are misreading it, but nevertheless all I am really trying to say is that, from experience, and not just from one particular ground or referee, I have witnessed the situation that I described on literally hundreds of occasions all over the country.
But I'm a laid back kind of guy, so I am more than happy for you to believe you're right and dozens of refs all over the UK to be wrong.
Either way, whenever I have personally been given a PAIR AGAIN - FIRST BIRD ESTABLISHED then I have always accepted those referees decisions without argument.
Yeah, it's all good and i am also pretty laid back, so don't think i am getting upset. But...I am not misreading anything..I am reading what the OP wrote...nor am I misreading the CPSA rules as posted above. In the instance that both birds of a pair are broken with the first shot, nothing is established and the pair is taken again.
I am well aware that you are extremely experienced, which is why I found it so hard to believe what you wrote. Considering I haven't seen the exact instance we are on about THAT many times by experienced shots, perhaps we are at crossed purposes.
You are absolutely right, without question...IF one of the birds is declared a No Bird. So you shoot the high bird, but the low bird is declared a No Bird...then you would get first bird established, Pair Again..
The reason you can't get an established bird, if both are broken together.,..is because, if they are broken together...you cannot "establish" which was broken first...
That is not to say that your example could be attributed to a shot before the peg, where as you say, the second bird was broken by clay fragments etc. This would not look the same and of course the ref would probably give you the first bird and pair again.
I am on about the double kill often gained by inexperienced shots, not irregular targets for experienced shots, such as yourself.
