If anyone is interested the results have been posted by Vortex now.
Overall, we did better than I thought and way worse than we should have. We wound up 22nd out of 57 teams. 53 finished the event. Some teams didn't finish due to heat and injuries.
It was a great experience, humbling, and very educational. I will likely plan to do this event again as it was a lot fun. We had a lot of issues at first with communication, spotting, and working through the shooting pace. As the day worn on we did much better but still had a long way to go. My brother had zero experience with LR shooting, spotting, etc so I had to give him dope and quide him through the entire process as we shot. All in all he did great and shot pretty well, but he didn't find targets easily nor spotted well for me. So as he learned and adapted to the whole ordeal he was gaining a lot of momentum toward the end.
The last station had a 1725 yard target and we decided our score was so bad we would shoot the target for fun. I had not shot this far, so why not. Neither of us connected but we worked right into the elevation by the 3rd shot. We connected with the bonues and hiked to the finish.
It was awesome and tough. We started at 0945 and fought 90 degree heat the entire day.
