I shoot 1000 yard BR and I like this answer. I use a 15x55 Nightforce (first model). It has a bigger dot in the middle and if I shoot 45x it floats the white patch. It makes it easy for me to center up. I haven't found the need to turn it down below 45X. MattShootDots said:If the heat waves (mirage) is not like you're looking thru a swimming pool to the target, MAX power is used on my scopes. As my ability to distinguish the number lines diminishes, so does my power setting. That said, I will only go down just so far. I have been down to 25 power, however, that is unusual. Most of the time IF I have to turn the power down, 32-35 is usually low enough to distinguish the lines.
