If you are talking about restrictions on long guns IN INDIANA, please post a link to the ones you have read. As far as I know there are no restrictions for long guns in vehicles in Indiana unless possibly hunting regulations.
There are plans in the works for a OC event in Indy including LONG GUNS.
Don't know anything about Full Auto regs, plenty of places to find it, hope you find your answers.
