He and his guides liked to exchange info on what rifles and bullets their clients used, and the results, and since those clients took around 30 elk a year, I thought this might be statistically valid info. So I asked him what cartridge he thought was a good minimum for elk, and he said, "Two-fifty-seven."
I asked, "Roberts or Weatherby?"
He said, "Either one!"
Although the 257 Roberts is my favorite cartridge I always thought it was a little on the light side for elk. Maybe I'm wrong.
