[QUOTE="kiwi3006, post: 306100, member: 8927"] Using your conditions and a 100 yd zero my program gives 13.3 MOA comeup. This program has worked accurately for my 7mm mag out to 600 yds. I think Bravo 4 had the right idea. What is your zero distance? Another thing that happened to me the other day was a strong wind coming up a slope UNDER the bullet and lifting it. It meant I was 2 MOA high at 617 yds. I wonder if something like that was happening? The JBM site has a free download called Al-Bal. I have used it and it gives results similar to JBM and my program. It also allows you to use G7 BC data as well. Stu. [/QUOTE]
