To me the 2nd shooter is confirmed with the time signature of the crack boom being different in the series of 5 shots verse the first series of 3 shots. Additionally the sound of shots (as heard from the podium) is also different for the second set of 5 shots in contrast to the first 3 shots.
However, what we are missing here is the frikken location of shooter #2. Can someone confirm the time signature location for me. I mean I think we are all pretty clear on the ~ 140 yards for the first 3 shots, but the second set of 5 are further away right? What’s the distance of those 5?
