Michigan changed the shotgun zone to limited firearm zone back in 2014 (I believe) for the southern half of lower Michigan. Now you can still use shotguns, muzzleloaders, etc..., but also straight walled cartridges 35 caliber or larger between 1.16" and 1.80" case length. This now allows guns like the 450 Bushmaster to be used along with some lever actions.


I have used a 257 wby mag in the rifle area up North and use Muzzleloaders, rifled slugs and this summer bought a 450 bushmaster to try out in the limited zone.
