Good luck with that, but you're state has a lot more flexibility than the southern zone 3 up here in Michigan. Down here the only firearms allowed for our deer season is a shotgun, muzzleloader, or a handgun that's at least 35 caliber. That requirement, just like your more flexible one, was designed to lessen the chance of projectiles going a mile or more in areas that are highly populated. Just like down in Indiana, especially the more hillier southern half, our area also has a lot of hills where a responsible hunter could use a centerfire rifle like we're allowed up north. In fact, we can use any centerfire rifle the rest of the year for varmint hunting and the reason that is allowed is because there aren't a lot of hunters out doing that compared to during deer season. Good luck and I'll sign your petition, but it may not get you what you want.
