Very first big game rifle I bought, in 1975, was a Ruger M77R. I mounted a 3-9x on it. Next was a Browning BLR .308, in 1978, and I mounted a Bushnell Banner 1.75-4.5x on it, and I've killed deer from 5 ft to around 400yds with that setup. Most of my big game rifles wear 1-4x, 1-5x, 1.75-6x, or 2-7x scopes. I've got a few that have 3-9x, 2.5-10x, or 3.5-10x scopes, none over 10x on top end, IIRC. Of my two longest shots on deer: one was made with a Nikon Pro-Staff 3-9X at 728 yds, laser measured, and the other, just short of 600 yds with a 1.75-6x Leupold with the heavy duplex. I don't own a scope that I twirl the knobs on, but several have some variety of drop compensating reticle.
