Quick question for anyone that might have the answer. With the instructions to determine drop the scope uses your drop at 750 yards and a bc. Well it tells you to adjust your bc x amount for going upin elevation or down in elevation above sea level. Now my question is can I just put my information into jbm ballistics to get my 750 yard drop in inches and keep my bullets b.c. the same. I feel like this would be much easier. Make a chart for drops at different elevation and say I go up to 10, 000 feet and mu 750 yard drop is 145 inches with a bc of .550. I couldnt see how it could confuse the computer any? Any input would be great.
