The last thing we (shooters/hunters) need is another cartridge. If you can't get it done with the cartridges available, you've got FAR bigger problems than anything a "new cartridge" is going to solve.
How about just better utilization of the cartridges available?
How about making fast twist as a standard for smaller bore calibers, for one recommendation; 1-8", 1-9" for .224", .243", .257", minimum, as the new standard?
How about smaller, lighter platforms for many of the otherwise available rounds? Something like a mini-Mauser action with a 16.5"-20" tube (a la the Mark X MZ CZ/Interarms rifles) in a lightweight synthetic stock, with better rings/bases options so the whole thing comes in WELL under 6#, and in something like the 6mmPPCUSA round, and/or the 6.5Grendel, etc.?
How about honest-to-goodness "youth" versions of the standard rifles; i.e., a shorter LOP and tighter grip option on at least most if not all the "standard" rifle set-ups?
How about making USEFUL improvements to what we actually have and that can/does work well, instead of more BS cluttering up the background?
As far as the .277" bore on the '08 case, 65, just send what is VERY likely an M70 action in 7-08 to Pac-Nor or any other 'smith/barrelmaker of your choice, have them rebarrel it with a .277" tube, run a .243Win reamer up it's azz, stamp it ".270-08Win", or ".270OCD", or ".270WGAF", or whatever your pleasure, resize .308 or .243 brass to .277" using standard (but set SHORT) .270Win dies and go forth thinking yourself as the only enlightened rifle-soul on the planet? Obviously, any semblance of sense isn't going to percolate through your skull, so just go off into delusion and make the world your own personal puppet by having "the only True Grail", and rock on.
