Try to google BEST OF THE WEST and go to the ballistic calculator. Real easy to use . You can even do 25 yard intervals. We use this program all the time for long range deer hunting. The program will go up to 2000yds

Ok, thanks. I have tried many of the computer programs. I think the problem is my scope..Nikon 4-16 tac. It says 1/4 minute adjustments, but it is closer to 1/3 minute per click.
