I've got a Nikon Range finder that is supposedly good out to 1000 yards in ideal conditions. In my experience it has typically only been able to reach out to 700+ yards. That being said I was range finding to the side of a building, not a small target. I'm not too confident that I would be able to get an effective reading out past 500 to 600 yards for a small target. My problem is that I don't have a range where I can practice out to 600 yards. At my rod and gun club the longest rifle range only goes out to 300 yards. I'm not sure what to do at this point. My .270 will shoot a sub MOA at 100 yards, so I am hoping to hold just under 3" groups out to 300 yards. That being said I know that there is a big difference between 300 yards and 600 yards. Can I even hold a 6 to 8 inch group out at 600 yards?? Not sure at this point, but I'm wondering if I shouldn't invest in some new glass with higher magnification. From what I'm hearing from some of you the rifle is capable of doing it's part...the question is can I do my part. My eyes are not what they used to be.
