Yes, a shotgun can be put in a rifle case. Most shotguns are longer than rifles, so many rifle cases are made to be long enough to hold them. But it's important to make sure that the case you choose fits your shotgun in terms of size and shape. Some shotguns, like ones with long barrels or big stocks, might need a bigger case to fit safely. Before you buy a case, you should always measure your shotgun and all of its parts to make sure you get the right size. It's important to follow safety rules when putting a shotgun in a rifle case. The shotgun shouldn't be able to fire, so it should be empty and the action should be open. You should also make sure that the gun's ammunition is packed separately and is hard to get to.
