There are number of calibers that, as chambered, are long in the neck. H&R has some and Weatherby did(does) it on purpose to reduce pressures. In a single shot you may be able to seat out, if needed, because there is no need to keep OAL length to feed from a magazine, etc. It 'might' work fine at the recommended length anyway.
On my Hornet I was tempted, and a friend wanted it as is so it is his now; but it is true that a .223 can be loaded to any of those smaller cartridge velo levels and still have the full load potential. If I was still wanting to shoot a .22CF I think that is the way I would go.
