[QUOTE="JARHEAD1371, post: 472348, member: 12950"] I'll pass on the advise Jim See gave me when I was developing my load. LEAVE THE CHRONY AT HOME!!! Shoot your groups at 300 yds and go from there. If you see a good one at 300, move out to 600+ and see how it does. When you find a load that groups consistently good at 800+ yds you will have a low ES. Then shoot over your chrony to see ABOUT what your velocity is, if you use a ballistic calculator for drops. That will get you close and you can use your actual drops to fine tune your velocity. After I did this I easily found a load that shoots 2.5" at 800 yds all day. I was just too concerned about the numbers the chrony spit out. [/QUOTE]
