We must also remember,when Jack did most of his hunting and writings,a lot of things have changed since then.A whole new line up of cartridges,powders and bullets have been developed since his time.The cartridges he liked back then are even better today than when he used them and who knows what he would choose as his favorite if he had today's choices.When I look at some of my old reloading manuals from the 1960's I think to myself,"That's It?"It was a lot easier to make choices back then.
