Pardon my ignorance, but how are unlimited sighter shots taken with alternating shooters and when do the shooters go for record. What if one shooter decides to take more sighters than the other. This doesn't seem to work out with time restraints. Perhaps the Protocol for pair firing only uses two sighters per shooter. I understand the requirement is 45 seconds between each shooter? I would like to run one of my matches pair firing and need to know all I can to run one properly. Is there any information on line as to properly run a match using pair firing?
