www.orpci.org has put this match on a few years now. It's a lot of fun- nothing too complicated. They even have a division that you can use a PCC instead of shotgun if you'd like.
Registration is on site, I believe from 0900 to 1000 central time. Shoot either Friday or Saturday, each day is run as it's own match. Published round count is 105 rifle, 105 pistol, 55 birdshot.
$25 per shooter match fee.
I've shot this the past two years and it's a good time.
