Well, the match is over; I didn't shoot all that badly (low to mid-twenties). Being unable to take a deep breath didn't bother much. When I last worked on the 52, I lost the magazine latch button and didn't notice until I went to pop the first mag out (the button is on the bench). I had to shoot the rifle as a single shot and I think that helped me by slowing me down. I did not shoot as well as my shooting partner but that's simply because he is a better shot than I!
Just club match, not much more than a practice session but this kind of competition is what feeds those national level matches. GD
