Jeff Cooper was the "real deal". Controversial, you bet, effective, you bet. You could disagree with him but you were going to lose. There is no substitue for experience. He and Keith have been and always will be correct in their choice of calibers.
As has been said about Davy Crockett, "he wasn't always right but he was always certain". Such can be said about Cooper with the caveat that he was often as right as he was certain.
I pray God be with his family. Another legend passes.
