There are times when a 4X is handy, as in seeing twigs that are closer to the animal and threading bullets into the vitals at distance but more power than that has never been needed on any big game rifle - that I've used. Binocs are for spotting and counting points - scopes are for shooting.

When guiding, I was constantly telling clients to turn down their scopes so they didn't get 'caught' at 9X in the bush.

The 'best' variable scope for a 9.3x62, I think, would be something like a 1x-3x, 1x-4x or 1.5x-4X. Once powers get higher, having them in the wrong power setting starts to happen. In fixed power, a 3x or 4x is about right, in my opinion.

All that said, I do like the 9x setting of my Burris for load testing- even though increasing the bull size and using 4X gives the same groups sizes with the same loads. Being able to see the bullet holes with the higher magnification scope is handy, even though the spotting scope is sitting right beside me when checking loads.
