Tim, I asked the DNR about stump shooting a couple months ago and it is absolutely not allowed on State land. I asked for distinctions between State Parks, State Recreation Areas, and just plain old State-owned land and they couldn't find any. If you're stump shooting on state land, have a hunting license and tell them you're hunting, not stump shooting. You also need to be careful about saying you're hunting, as some State land is posted no hunting for most of the spring and summer. I know this pretty much sucks as it's difficult to find enough land to stump shoot on, except for state land, but there it is. You just can't do it. One more harmless, fun activity legislated against!!
