    I had to sight my 7-08 in at 60 yards. I'm shooting 140 grain Cor Lokt. At 60 yards I'm shooting 1.5 inches high. What should I expect at 100 and 200 yards at this sight in?

    Assuming the center of your scope is about 1.5" above the center of the bore, my JBM app says you'll be hitting about 2.5" high at 100 and 1" high at 200. The bullet should hit zero again between 225 and 250.

    I have had to deal with short target ranges,,,, Sadly at 50 yards you are basically bore sighted in.

    I would guess that BluEyes number are about right, but you really have to find a longer range to confirm.

    There are many things that can effect where your rifle will actually print.

    Just plug your numbers into the program listed above in post #2. There isn't enough differnce between 308 and 7-08 to matter so it will be essentially the same.

    Using a zero of less than 100 yards is not nearly as accurate. You may "think" your sights are perfectly zeroed, but minor errors don't show up until you start shooting at 100 yards or farther.

    If a range of only 50-60 yards is the best you can do I'd personally zero dead on at 50. That will put most modern rifles about 1" high at 100 yards. I wouldn't attempt a shot at game much farther than 100-125 yards until I could actually shoot at targets at longer ranges to know fore sure where I'm hitting.
