Hi when did Rem make 458 win mags off the shelf, I was looking for a 375 H&H and went to a old timer that was selling out. I asked him if he had a 375 and he said yes but he had a big bore that he has been trying to sell for some time but no one would buy It...... not even pick it up... 458 win mag.... I picked it up and wow... light...action slick as glass I walked away with it for 500 buck.... this goes with me everywhere for the last three years what a gun and this gun was new! when I bought it. But I went to Rem web and they do not make 458 mag? And the Trigger out of this world for a big bore....
