LOL, funny stuff Sir Ron, you know, one of my PH's in Africa had a factory FN Browning Safari 458 WM chambered for 450 lott, action opened up too, the whole nine yards, saving grace is it already had the 458 WM throat of course, i left him a dozen rounds of my 458 WM+ loads with 404 Hammer at 2518 fps at 3.575 COL, he used one of those on that 3300 lb bull Giraffe in the video he sent, good stuff Sir.
