Actually, If I am not mistaking…. In Wisconsin.. -you can sight in the day before at designated ranges (but why wait until the last minute?) -Also, you are allowed to hunt waterfowl the day before
I believe the MN law reads, you may not be outdoors with a firearm and ammunition, which would include shooting, 5 days before and 2 days after the season for watever area you are in. You can use gun ranges.
