Had a conversation about this with a game warden in my state last year. It was turkey season and I had shot a turkey with my bow. I was at my truck with bow stashed and turkey tagged about 9 a.m. when a warden pulled up to check me.
Since my brother was still hunting, and would be for the rest of the day, I suggested to the warden what I planned to do -- go looking for morels and do some stump shooting at the same time. He didn't know what stump shooting was so I had to explain it. Also explained that I'd leave my broadheads in the truck and just have steel blunts. What would he do if he came upon me while I was stump shooting, I asked. Probably cite me for hunting turkeys without a valid permit, he said.
Obviously, I didn't carry my bow with me when I went looking for morels. Have had this conversation with several other wardens since. Again, most had not heard of stump shooting. ( I explained it and presented them with a copy of our Wisconsin Traditional Archers magazine, which is titled, The Stumpshooter).) Regardless, they said it would probably be officer discretion as to whether to cite for illegal hunting. My fallback is to say I'm hunting coyotes, which are open year around here. I always have a valid small game hunting license,of course.
Long story short, I still stump shoot, though not during turkey season around here. Guess I'm willing to take the chance and spend the time and money to defend myself in court if the warden's interpretation of what I'm doing doesn't match mine.
