I'm not aware of a .45 Magnum. There is a .44 Magnum.

The 44 magnum is typically a revolver round, very high power. The 45 ACP is typically used in semi-automatic pistols. The 45 ACP is not as powerful compared to the 44 magnum (mostly due to the amount of propellant in the 44 magnum compared to the 45 acp).

45 Winchester Magnum. Almost but not quit as powerful as the 44. Slighly larger .452 vs .429. It is a lengthened 45 ACP shell.

What else can I help you with?
