.223 Rem
Exciting stuff. I'm very interested in the cartridge and seeing if this sparks a new advancement in cartridge and firearm design. The .277 Sig Fury is an awesome round. Reloadable brass with a steel case head to handle all that pressure. @Podmonkey , you said they reinvented the 7mm-08 – sort of. It's doing out of a 16" barrel what the 7mm-08 can do out of a 24" barrel. Give it a 24" barrel and it's matching the .270 Winchester in a much smaller, short-action cartridge. That should mean reasonable recoil, very flat trajectories, and solid lethality downrange.
