You are not allowed to use lead shot for doves PERIOD in MN. When the season was first proposed, some of us opposed it, since there really isn't a huntable population of doves in MN, and, while the "city people" who seem to have much to say in legislative matters involving the DNR here might not be able to identify a ruffed grouse or woodcock, they sure as hell knew what mourning doves look like. They are still bitching about a season on their "songbirds".
The steel shot only rule came out of no-where, and was something hunters who fought for the season on doves didn't and couldn't see coming.
Remember this date-Sept. 1, 2011. That will be the first season MN goes non-toxic only, statewide. Those who wish to rally against it, are too late.
Best,
Ted
