I too would recommend the Nikon Prostaff 2-7 or even a 3-9 if you want a little extra power. I have a 3-9 on my son's 243 and it is a nice scope.

I would think a Bushnell Elite 3200 or a Burris FFII, should be fine on a MLer. Not saying there is never a problem, buy I have never read that they should not be used on a MLer. I currently have a 3-9 FFII mounted on a 6 1/2 lb .504 White MLer. Only shot it a few time (currently waiting for bullets). Only time will tell.
