Re: first time at 700yards
Fun, isn't it? You will have to find out whether your scope really is tracking correctly or not. Get a very accurate zero at 100, and start cranking on the dial. Measure how much elevation you get with the marks on the dial. That will let you know what it is doing.
Then, get groups at each hundred yard distance. Figure out how much elevation you need for each yardage. Then you will be able to make a drop chart for your rifle and load. No more guessing. If you use a program like JBM (online), you will probable need to tweak the speed and bc to get the numbers to match your real world data. You can then print out a drop chart and you are good to go.
Let us know how it goes.
