As far as strange caliber restrictions go, I think Indiana now takes the cake. And no, I'm not saying that because as a 270 fan I dislike its exclusion. Okay, maybe I am.
Seriously, though, if someone would kindly explain the reasoning behind this, I'd love to read it.
At least it's a step in the right direction. Maybe once the game department sees no harm is done, they'll open your gun season to all .22 or .24 and up calibers.
