I liked this old quote, "Bob Hagel, You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong. "...
I’ve got some of Hagel’s books, and look at them often. He was pretty content with a 7 mag or a 300. He also had no qualms using (much) bigger rounds at times. I think he was pretty recoil tolerant. He is a good read and appeared to have a lot of field experience to back up his opinions.
