LOL, Nice Sir Ron, as the river reeds gave way to the wind last Oct 9th in the Mbarangandu Game Reserve, Tanzania i let loose a 750gr TSX at a sight regulating 2076 fps into an old river Dagga Boy at 16 yards from a 577 double, i saw and heard the pain that buzzsaw caused the old beast as it entered his left last rib at a hard quarter away, he hit the sand and began his death bellow before i could get the sight back on him quickly moving to my left for a solid through both shoulders.
I have no doubt the 450gr TSX at 2450 fps would produce the same from the Great 458 Win Mag+............with the added bonus of three rounds held quickly in reserve.
No doubt. Perfect. Be careful with those 500-gr TBSS at 2350 fps if herd shooting and you do not want to pay for two with only one shot. I once bagged a cape buffalo using a .500 Mbogo. One shot killed it at about 75 yards, broke the onside left humerus (stoutest bone in the buffalo) and passed through the heart, did not exit.
The second shot at a bull on that hunt in Tanzania was on a hairbrained command from the PH for me to shoot a bull when he ran through an opening 150 yards away,
while I was perched on the side of a termite mound with wobbly-twig shooting sticks that collapsed as I shot. Thus I was caught off balance twice in that incident. First for undertaking it at all. One drop of blood was found, believed to have come from a buttock graze wound on the bull.
I felt bad then, but hey, it saved me another +$5000 taxidermy charge and someone else was picking up the tab for the B-Team PH and trophy fees. Sometimes it would be better to ignore a suggestion from a PH, especially if you are paying him.
My first cape buffalo in Botswana also bucked like a rodeo bull when hit through the heart and the onside, left humerus at 50 yards with a .416 Rigby. He launched straight up on three unbroken legs also.
A termite mound in Botswana, where no shooting sticks were set upon the slope:
That was a 380-gr GSC FN solid at 2506 fps MV that exited and probably passed through several leadwood tree trunks after that. The Tanzanian bull was taken with a .510-cal., 450-gr GSC HV (soft) throttled back to 2650 fps MV instead of +2800 fps, because it shot 0.75 MOA at the slower velocity instead of 1.5 MOA at top end. Thus, not entirely because I am a recoil wimp.
The .458-caliber 450-grain TSX at 2450 fps would be the best insurance policy, 6,000 ft-lbs is plenty ! Most likely to kill one bull with one shot and not wound any other fauna and flora. And such a trim and handy package is a .458 Winchester Magnum M70 !
