Normally we have 2 or 3 places that have weekly matches, but this has been an off year. I know it sounds crazy, but with the election and panic ammo buying frenzy, seems as many lost interest in the local matches when ammo got tougher to find back around Christmas time.
Piney gives the most organized match in the area, the other ones seem to come and go and are often less "publicized". Many of these style matches may not have appropriate insurance and licenses, which is the main reason they seem to come and go.
The funny part is most of the people that shoot the factory sporter matches at Piney, never attend the "other" matches. There is a few that do both, but for the most part there seems to be two different crowds of shooters that attend the "factory" sporter matches.
What we usually find is someone will start a match with a few buddies. A few weeks later they start having 15-30+ shooters. Usually these matches are on Friday or Saturday nights. They often start around 7 and run into the early morning hours.
Best place to find out about local matches is to hang around any gun shop that sells match ammo. When the local matches start up, many locals buy ammo locally and its the best and fastest way to find out where and when a match is being held.
Each match seems to have a slight deviation of the rules, but for the most part, the rules are as you posted. If you have never been to one, its amazing to see how accurate these factory sporters are.
