It varies from state to state and would have to be more specific as to what other guages or calibers are excluded. Only in recent years have they allowed centerfire handguns and very specific as to cartridges. Even more recent, center fire rifles in the "Lapland" counties of Iowa. This is the bottom two tiers of Iowa counties or as they say, where Missouri laps over into Iowa. It's really all in the details and really don't have them at this time. The .410 exclusion has been in effect for as long as I can recall.
Be Safe !!!
