[QUOTE="Buffalobob, post: 164253, member: 8"] What I do for temperature and altitude is I run JBM/Eskimo for what I have shot in reality and then I save that file and I run the same data again but change the temperature by 10 degrees and run the program again and check the difference at 1000 yards. I then run it again for 10 degrees less and check the difference at 1000 yards. I may run it for even +/- 20 degrees and check those differences. I then make a little note for my drop chart as to the MOA change per 10 degrees. I then repeat the whole exercise of resetting everything to my known dialin conditions and run the programs with a change in altitude of 1000 ft plus and minus and for 2000 feet plus or minus. I check the differences and make a note. For the 7AM at 1000 yards the change in drop is : 10 Degrees F = 0.1 inches of drop 1000 ft elevation = 0.2 inches of drop [/QUOTE]
