Seems the 22Creedmoor would be the twin to the 22-243 Middlested.

Parent case is the 6mm Creedmoor...easy enough to just neck down 6CM brass in a single operation, or you could do it in two steps with the appropriate neck bushing dies. Making brass from 6CM is an attractive option as there are several top notch manufacturers, including Lapua, who make brass for it. For now, Hornady is the only one that I'm aware of making factory brass so far.

Edit: Good article on the .22CM here: https://www.primalrights.com/library...s/22-creedmoor
