If you're taking a spotting scope, I recommend you look at something like a 3-12X50. That should be ample for big game up to even 800 yds. You'll have much better contrast.
That assumes you have good vision or can wear correction. If you have vision problems then you may have to go to a higher mag.
That's something I haven't thought about. My vision has always been 20/20 or better but lately my shooting eye is getting a little double vision. (getting older sucks!) I have a 12x Sightron on my 223. I'll take it to the range tomorrow, I always need an excuse ;)
