MIssouri is very gun friendly...no case required and you can walk into a gun store and walk out provided you pass the background check. I've hunted in WI and always kept my gun unloaded and cased...that is all I know about WI. They are pretty finicky about purchases with regard to any minor history and I beleive there is a waiting period on all purchases...thats what I could discern while buying a hunting license.
