Sounds like you are close to MRPC! lol I'm a member there as well as a past USPSA match Director and board member. The club has changed a lot and there are probably better options for you. Clinton county farmers club is near Wilmington and is a great club. They shoot 3gun, IDPA, USPSA(pending), shotgun games, etc.
It sounds like you are not set on a particular game? We are mostly USPSA Oriented on this forum and SW Ohio shoots more USPSA than anything. I am also the USPSA Section Coordinator for Southern Ohio and will be more than happy to get you any info you may want on the sport. You can go to uspsa.org and use the club finding feature to find info on all local clubs.
Generally you will find you can shoot a USPSA match every weekend somewhere in the area.
