Mule Deer is dead on on the Lost Classics. I talked with Bradford about the article of Jack shooting his first Dall Sheep on Black Rapids Glacier in the Alaska Range. He said that there was another Jack O'Connor who had the same name that Jim Casada put in the Lost Classics book. Jack never hunted in Alaska for sheep. He did hunt Brown Bears in South East and on Kodiak but he never hunted sheep in Alaska.
Jack O'Connor 2 book Collection of hunting on Three Continents is a good book. I would argue that if a person has access to the Ken Amber Gun Digests through the years that you get a lot of great articles. Sheep and Sheep hunting is still the book that I have worn out two copies of.
