It's been done. Called the 20 PDK (Prairie Dog Killer). There is a 22 and a 6mm version. Actually, the PDK is a bit of an Improved 6.8 case, moving the shoulder forward about 50 thou and a 30 degree shoulder. I have the 6mm PDK built as an AR match rifle and it works very well. Used to be headstamped cases available for it but the guy that came up with the cartridges and sold brass folded up his tent. Reamers and dies should still be available.
