In two days from now (Saturday, April 13/24), Part 1 of a 2 part series, is titled: "Why I Still Promote the .458 Winchester Magnum". It contains a bit of personal history with three of 'em, and handloads, in particular from the CZ 550 and my current Ruger No.1H; in case anyone is interested.
Thanks Sir Ron for all of the recent work related to those historic books, along with your much appreciated comments.
