The 257 Roberts thread made me think of this. I say it’s the 30-06 with the 270 close behind.
In the post title, he doesn’t specify east or west, high or low. In spite of the fact one can kill a deer with about anything with a barrel, this is an intellectual exercise.
What is “the best”? That means one specific cartridge.
Though I’ve not had one for years, I would probably nominate the .308 Win which probably has enough OTC loads to fit about any situation aside from any hand loading one could do. Not too powerful but fairly flat also..
