Check Iowa Code section 724 and DNR regulations for clarification but as I can recall there is no license to own a shotgun in Iowa and, yes, shotguns do need to be cased (or dismantled) to transport legally.Calling the shotgun a rifle is enough to bely how ignorant of firearms the writers were. Before I write some hate mail, I wanted to check: 1) Do you need any kind of license/permit for a shotgun in Iowa? 2) Do shotguns need to be locked/cased while transporting?
The lawful transport of long guns was explained by a DNR officer in my hunter education class. A shotgun must be unloaded. The shotgun must also be in a case or in at least two pieces before being placed in or on a vehicle. Placing your shotgun on the tailgate of your truck so you can free your hands to load up your catch will be a violation. Take the time to either remove the barrel or stuff it in a gun sock before doing so.
