If I remember correctly back in the late 1980S,the then new .416 Remington Magnum trumped the .458 Winchester Magnum,and sent it off to the side of the Magnum road,then the gun writers buried the .458 Winchester by trashing it with negative press.

I load my Model 70 down to Marlin 45-70 Max loads for Deer&Bear, I never had one get up or run.
