With a couple each 7x57 and 7mm Weatherby rifles, a .270 is of little utility to me. So my short answer is None.
That's about where I am. 7mm's in several chamberings then .30 then .338 so there is nothing to offer in that caliber. They just don't make animals that cut off with one cartridge and then apply to the next caliber downwards.
When truth is ignored, it does not change an untruth from remaining a lie.
