FN Brownings are very valuable and the best large factory rifles ever made, but .458 is only good for elephant, rhino, buffalo and just too much for anything in NA. My CZ 550 Mannlicher 9.3x62 is more than enough for anything on this continent.
Last .458 I examined was early 50s Winchester 'Super Grade', luvly classic rifle, but what to do with that darn caliber?
