I am pretty sure the 270 is not the offspring of the 30-06. They are brothers
out of the 30-03. And both have killed an immense amount of game.

If your 270 brass does not last long, you are probably overloading or have a sloppy chamber.

If you shoot deer with a 270 using 130 gr Nosler Partitions, you will never need another caliber.
