Only problem I see with the team thing is isolating the teams from each other so they can't hear the wind and range calls. But unless guys are shooting the same rig it isn't exactly relevant. It would only take a few targets to figure out relevance of the others wind calls. I suspect some of the targets will be difficult to range too. So, I am leaning toward lone shooters with the group doing the spotting. It's not going to be a competition with score but more of an exercise in competent hunters finding the limitations of ability and equipment. I think we will limit this to 6 shooters. If can get through each shooting position in 15 min for all 6 shooters it will take 6.5 hrs to shoot 25 targets. Thats not leaving any time for transition to the next target.
