Unless I'm hunting in dark timber, I normally keep my scopes at or near their highest power setting on my 2-7x33's. On my 300 win mag (mostly used for long range), I normally keep it at its highest setting, which is 9X. I recently replaced one of my rifle scopes with SWFA SS 10X scope (7mm-08) which I have grown to really like (especially the MOA reticles). I will soon be moving it to my 300 Win Mag and replacing with an SWFA SS 6X. Both rifles are normally kept at max power and I like the simplicity of fixed power scopes on hunting rifles. Some will say that a fixed power 10X scope is not the best for hunting but my old 66 year old eyes appreciates the magnification.
