6x45 is a .223 wildcat, necked up to .243. You're limited on what bullets you can shoot in the 6x45 due to ogive length and case length, which is why the 6mm AR (6mm Grendel) makes a lot of sense with a shorter case, more case capacity, and the ability to use long target or hunting bullets with high BCs.
