The cartridge that you use does not in any way make you more or less of a hunter.Just because you use a 30-06 does not mean that you are by any means a better hunter than a fellow that uses a magnum.A hunter should be judged by his skills and not the cartridge that he uses.As far as the 30-06 having taken more big game of every north american species that is a very broad statement that can' t be proven.If however you look at the tenth edition of Boone & Crocket records(the only one that I own) the 30-06 leads in entries for 8 species.The 7mm mag has more entries than the 30-06 for 13 species.The 300 mag has more entries than the 30-06 for 14 species.
