In MB, FMJ is illegal to use on what's considered big game, whereas coyote is considered a furbearer, so FMJ is fine, providing you're shooting them under a trapping license, not during deer season under a hunting license. I'm not sure what the legalities are in other provinces but suspect AB and SK are the same.
But in regard to the OP's question, even a 308 with FMJ's can leave some pretty nasty holes. If the object is to kill them, then it'll work just fine.
No FMJ in Manitoba for hunting while under a hunting liscence. Not sure for trapping.
