I tend to hunt open country where shots have averaged 350+ over the decades. For years, my scopes of choice were 3.5x10 Vari-X-IIIs so most longer shots were at 10x. Today, I prefer more magnification and routinely shoot 15-18. I tend to keep scopes at 6x before setting up for a longer shot. In the country I hunt, this has never been a problem….
