Here is where it starts. Shooting at the steel buffalo at 800 yards, target 1. Again, shooters on the left are firing, while those to the right the canopy are setting up. There are two sets of targets at each distance, so two groups are able to shoot at the same time. This is the "red" target. "Yellow" is shooting down at the next canopy at a completely different buffalo.
The targets are fitted with two-way radios with voice activation on the target end. When at hit is made, the clang triggers the radio and the scorer hears the still-ringing target. Usually. In the rare occurrence of a hit not triggering the radio, there are enough people watching to call a hit. Its all about having fun, not rules and procedure.
When one squad is finished shooting, the scorer calls out the number of hits for each shooter, then calls in the next squad. Then she simply rotates her chair and runs the group that is ready to shoot, while the first bunch clears the line and is replaced by the next group. Clockwork.
At 800 yards, the bullet is in the air for about two whole seconds, which seems like an enormous time. You have time to take the shot, follow through, wait for the to smoke clear, and then listen for the "clang". In the case of practice days, the radios are not hooked up yet, so you get another whole second for the sound to reach you. If the wind is blowing, as it often does, the folks down the line get to hear your hits better than you do!
