For elk, the area i hunt we saw elk at 600 yards last year, we just couldn't tell how many points, if any. Spotting scope would have helped probably, but didn't have one, and even if i did i probably wouldn't have taken a 600 yard shot because i've never practiced out to those distances.
I like the 165-168 grain bullets for the '06. That gun doesn't have the magnum velocity for good Barnes or hard bonded bullets unless you are pretty close as the 165 grain bullet usually drops below 2,600fps inside of 200 yards.
