[QUOTE="Darryl Cassel, post: 20803, member: 34"] Brent We do need the temp.& altitude you are shooting at but, you chart is falling fairly close to my Oehler ballistics program. I too, think it is a lower BC then advertised, plus make sure the chronagragh is reporting the speed accuratly. Your sight height should probably be programed in at 1 1/2" above the bore on that rifle also. Rerun the program using a BC of .450 and see the results that are given. Just a thought as I have seen many bullet manufacturer's report higher BC for their bullets then what is a real figure. Darryl Cassel [/QUOTE]
