I think the real question is why some have to bs
e so anal about this topic. The range I shoot at has a ton of new shooters and to them the .45 colt is a .45 acp and you can correct them til you are blue in the face and they still call it long colt. But if it makes some people hours and hours to argue over it well I uh ave bigger things to pass my time. By all means argue away but I need to go load some long colts.
