You can see all the way to tomorrow! Okay, that’s an exaggeration. Your long-range visibility depends a lot on conditions and your target. On hot days, when high magnification amplifies heat mirages, you may want to lower your magnification. But with the first-plane reticles in most of these precision rifle scopes, in most conditions you may want to increase your power so that your reticle references become more visible. Generally, our testers found that the most useful magnification range for a 5-25-power rifle scope is about 8-20-power. The additional magnification, on both the lower and higher ends, are nice features but may be too little—and too much—magnification for most shooters.
