I think the new range near Shades State Park has a 300yd range.
I now wish I could remember the name of the place... Sugar Creek Range, perhaps?
It's the second house towards the park from the intersection of SR 234 and CR 800S.
Quickest way to get there from Indy:
I-74 to Jamestown exit (SR 75)
Take SR 75 South into Jamestown
Continue South on SR 234.
Take SR 234 through Ladoga (10miles), across US 231 (10 miles), across SR 47 (~5 miles), and then another 12 to Shades.
$3 to shoot...or buy a membership.
