Tried searching but didn't find just what I'm looking for. I'm kicking around the idea of building a 6.5 Creedmoor. Idea is to use it for target shooting and practical/tactical type matches, something along the lines of the ITRC in Wyoming on the extreme side or USPSA MOR on the light end. So the question is, how much glass do I need? Do I need a 5-25 or will something lower powered serve as well or better for these types of competitions. I'm running a 3.5x10 on my .308 now. I just want to make sure I can maximize the potential of the 6.5.
