Greetings,
What we need to do with the 270 is to speed up the twist a bit to say 8.66" so it can stabilise heavier projectiles. Perhaps move the shoulder forward a bit and sharpen the shoulder slightly to increase powder space. Maybe change the bore from .270 to .276 as better projectiles are available. You would then have a better cartridge. You would have also invented the 7x64 Brenneke from 1917.
