What kind of group would you exspect or what kind of accuracey standard should I try to accomplish at the 700 yard mark ?
I use a kestrel 2500 NV

You have the the same stuff as I do. After you confirm the 200 yard zero and have enteresd the current bullet data, and field conditions. Then enter your range (700) in the target engagement page hit update and calculate. Then shoot your 700 group using that dope. If you are shooting under 1 1/2" at 300, that is under .5 moa. So at 700 you should see a group of 3 1/2" or less. I feel this is great shooting.
After you have your group at 700, measure the height difference from the center of group and your point of aim. Lets just say it is 3" low. Then on the first page of you NF program, hit " program options" and select "Tradgectory Validation". In tradgectory validation you will now enter your data and hit apply. So, we were 3" low at 700,... distance 700 yards, .. point of bullet impact -3...apply.
Then start the fun part, testing to see you are indeed on at all distances. You can go back in and do tradjectory validations at any time or any distance to 1000 yards. If you find you are on at 1000 but up or down a couple inches at 500 I would not sweat it. The deer at 500 won't mind if you are off .5 moa / 2.5" but at 1000 .5 moa is 5" and that could be a potential problem.
Hope this helps, have fun!
