Basically they wanted to do a local version of Top Shot. They had a blind elimination bracket, starting with 64 entrants over multiple rounds.
The first round was a straight 30 round bullseye stage. The remaining stages were basically simple action pistol type stages, some with prop guns, but you never knew what they would be till you showed up.
The opening rounds went on for about a week and a half. You basically could go and shoot each round/stage at your convenience on specified days. Once they narrowed it to eight people they did the final 3 rounds today to decide the winners. The last 8 shot head's up against each other in randomly decided brackets.
We shot a shotgun, and MP5 prop gun at one point. Targets were largely IPDA paper with a few falling targets and even a balloon on one.
