I'd recommend a membership at Marion County Fish & Game
www.indyrange.com
I joined this year and love the place... and you are a LOT closer than I am.
I go to the marion county range at least once a week and usually take my clay thrower with me. If you want to come as a guest send me a PM.
This week we are going down by Bargersville so we can shoot Ar's and some Tannerite, so it would have to be next week if you wanted to come.
I may take you up on that. I'm gonna check it out some time this summer, for sure. Their website makes it seem like its not open very often, and I work "odd" hours.
You get a key as a member. You can shoot from dawn to dusk.
