Unfortunately in MI to whitetail hunt in the lower part of the state, you need a shotgun or a straight walled cartridge with a case length less than 1.8 inches and at least 357 in caliber. (That's why the 450BM is so popular in Michigan). The state penalizes everyone for a few who can't hunt responsibly. 90% of the hunters are sitting in trees shooting towards the ground anyways. But I guess the DNR is scared people will sit on the edge of soy bean fields and launch a 300 Win Mag 500+ yards away if they take the restrictions off what we're allowed to hunt with.
Bolt action rifles in 6.5mm and 30 caliber make up the majority of my humble arsenal. I usually shoot 140's in 6.5 and 215's in 30 caliber. I'm a big fan of great BC's! But unfortunately we're not allowed to hunt with those in my part of the state.
I do however like the 450BM quite a lot in the limited time I've spent with the cartridge so far!
