What’s the story with mini mausers?

For awhile I’ve had a notion about a nice little mini action with a 20ish” barrel chambered in something like 6.5 Grendel. Light and trim, plenty for deer, and very low recoil.

Most minis aren’t really Mausers though, are they? If I recall, somebody did a beauty in 220 Russian some years back and shared it here?
