I have land down here as well, I farm. I have my own private 300 yard range out back with covered shooting bench and 1/2" alloy plate backstop with 5 feet of bermed clay in front of it. I can't find the steel with any caliber I shoot, 338 Lapua included. I get custom rifles built by John Pierce in Lansing, on the way to my getaway...lol
My 'go to Michigan hunting caliber is 308 or a 44 magnum handgun with an X bow in there somewhere. End of the month will find me turkey hunting on the ground.
The trick with Michigan (if you want to call it that) is being north of M46. North of 46, anything that goes boom works. South of 46 is shotgun, bow smoke pole or straight walled pistol cartridge in a rifle like a Marlin or Henry.
