So, I know some cartridges are (for the most part) interchangeable, such as .223 in a 5.56, or a 45LC in a .410, but just how many are there? Do certain .22s work in other types of .22s? Do certain .17s fit into other .17s? Some calibers are very close to each other, and some identical, I'm not looking for specific guns that are "multi-caliber," but rather different rounds that often work in the same barrel. Thanks in advance!
