In the state of Missouri Its perfectly legal to hunt with a black powder rifle during deer season. In all counties
There is no closed season for crows you are allowed to hunt any time of year
Some hunters use a muzzle loader because it offers more of a challenge than using a modern rifle. Also there is a different season for muzzle loaders therefore you can hunt during that season with it.
In most states but not all. Please check with your state game/wildlife department.
In Pennsylvania, after the regular rifle season for deer, there are additional hunting opportunities during the late archery season and the late flintlock muzzleloader season. The late archery season typically runs from the first Saturday after the close of the regular rifle season until the end of the year. The late flintlock muzzleloader season usually follows in January. Specific dates can vary each year, so it's important to check the Pennsylvania Game Commission's regulations for the current year's schedule.
