In a nutshell it’s a slightly shortened 270 WSM case (0.08” shorter than 270 WSM case) for utilization of high BC very long .277 projectiles in a standard length WSM magazine with 165gr to 175gr weight bullets. Rifles will have faster twist rates in the 1:8 - 1:7.5 range. Can’t really see the benefits unless you are constantly pulling the trigger and bucking wind on game at 700 yards plus. Another reinvention full of intrigue? Probably not, but this is another part of the new wave of rifle/hunting needs being sold to the public.
The odd part is, those new .270 heavy projectiles have a lower BC than lighter offerings in the .264 that already exist. They are decent in the .600 range, but you can get a 145gr 6.5 bullet that is over .700 already.
