That 200 grain Nosler Accubond in a (an? Because "8" starts with a vowel) 8x57 is a solid hunting set up. If I had only one rifle set up to hunt, this would take care of my needs. A well- balanced choice, and option.
I also like the 30-06 with 200 grain Accubonds. A well-balanced choice, and option.
Not sure if this response is solving any problems, but it makes me feel good that there are multiple effective ways to get the job done.
