Sorry, no idea what the rates are for sighting in. I think their trap/skeet/SC rates are pretty cheap but I haven't shot there, just spent waaaaaaaaaay too much money on guns- including a SxS last night!And you're right, they're only open wed, fri, sat and sunday.
Another alternative might be Crooked Creek (
http://www.crookedcreekgunclub.org/). They're up north of Noblesville. I've never been there, don't know much other than what you see on their website but plan on joining after the first of the year to have a better place to train my dog as well as shoot.
