The thing I do is to go to JBM
JBM - Calculations - Trajectory
Question #1 - Then I run my ballistics at different temperatures keeping everything else the same. I cut and paste the data into a word document because my memory is not good enough to keep track of that many numbers all at once. I can then find out what the change is at what ever distance I wish.
Question #2 Run your bullet and see what JBM gives you.
Question # 3 Do the same as question #1 except this time change altitude by 1000 feet and see what the difference is.
In case you think I have not answered your question you are right. You have to learn how to use a ballistics program just like all the rest of us.
