Had a scope on my 458 WM removed for a large peep site. With practice I am good to 80+ yards.I just don't trust any scope under heavy recoil. Had too many fail.

Confidence shooting with "Minute of Buffalo" 458 WM accuracy would be a h*lluva lot closer than the longest distance the iron sites are capable of. Thus no scope.

I agree. A scoped 416 is about the max rifle I want scoped.
Bigger bore bolts are usually close range affairs.
