Boy, this is getting into a real grey area.
As others have already mentioned, all data for a .35Rem points to 1.92" for a case length. The proclamation states between 1.18" and 1.8".

So how is the DNR officer that checks your rifle out gonna ensure you're complying? If by measuring the cases you have in your rifle, then you're good to go just by trimming the brass. BUT...if they've got a list of calibers handy they're gonna flip through the list and find that .35Rem is 0.012" too long and write you a ticket.
I know for a fact that the NoDak Game & Fish Dept wardens use a list of the standard commercial cartridges and their length/diameter (for our handgun requirements)...I can't say what the Indiana guys do.
Best bet would be to talk with one of the Indiana DNR guys since they're the ones who are enforcing it.

A loophole around that could be that your rifle is chambered for a wildcat cartridge using the .35Rem as it's parent cartridge. I'd bet that the game warden would want to see the name of the wildcat stamped on the barrel instead of ".35Remington" though.


Otherwise, as Alpo posted, having brass .012" shorter than spec won't be a problem for finding data. Start at the minimum loads and work up as usual. You might have problems seeing high pressure before you reach the manual's max loads if you're using bulky powders and loads that are near/at 100% load density. Just avoid those loads.
