There's a bunch. A quick search of Ammoguide.com shows 23 cartridges with rim width is equal to .441 ± .003 and case length is less than 1.76 inches.
For starters, we have the PPC line, some of which are factory standard rounds.
The Grendel cartridge has been wildcatted in every caliber from .20 through, I think, .35 caliber.
The .220 Russian, a stepping stone from the 7.62x39 to PPC and then the Grendel would certainly work.
The rim width and magazine length would also accommodate the .38 special, .357 Magnum, and .357 Maximum cartridges. These cartridges have a following in rifle and AR shooting circles.
