And in the rifle magnum ammo chart's "pipsqueak" column, there's the .22 Winchester Magnum.

There's other rimmed cartridges used in rifles that have "Magnum" in their name, but they originated in the handgun world.
If we're splitting hairs, the 224 Weatherby Magnum has a .430" bolt face.

The bottom line is that anyone can create a wildcat and call it whatever they want to.

I assume there's a procedure and fee for certifying/registering a new cartridge with SAAMI or CIP. And, I doubt they care much what you call your cartridge if it doesn't conflict with an existing one.

Re: What really makes it a magnum?

The first "magnum" rifle cartridge was the 375. It was invented in 1912, across the pond, by H&H. The belted cartridge's rim measured .532", which for many years was the standard that practically all rifle cartridges that were called magnums, used. And although to a somewhat lesser extent (i.e. the short magnums), it's still pretty much the same "case" today. That's the history.

But the actual "definition" of a magnum? Technically speaking, there isn't one. The closest thing I can come up with is a "connotation". For the less educated, a connotation is basically a thought picture that the mind conjures up upon hearing a certain word or phrase. And for "magnum", that would be: Large, powerful, ass-kickin, when compared to what one considers typical, or "standard", especially, but not limited to, a particular caliber.

Can anyone do better than that?

Good explanation.

So if Magnum conotes, "Large, powerful, ass-kickin," what the heck's an Ultra Mag?

I believe the first use of "magnum" was to define a 1.5 litre bottle of wine. Late 1700's or early 1800's was the time frame.

Yea, but there IS some debate about that. Some contend that it = to "2" regular 1 quart (or 1 liter) bottles. But that's really getting off topic.
