[QUOTE="Greyfox, post: 2347222, member: 10291"] I have used both. They appear to each use the same basic algorithm(JBL) to calculate drop values. Given identical inputs for pressure, temperature, and humidity and all rifle/bullet parameters I have found they produce calculated drops within .25MOA out to 1350 yards. I have also tested the G7,and GeoBallistics for which the same holds true. This is observed when there are “no” values entered for wind. The drop and wind corrections begin to diverge between the programs when wind values, and other advanced features such as CE(at the longer ranges) are enabled. The AB treatment of aerodynamic jump as it relates to wind drift, and elevation/wind values may be different by as much as 1MOA(in my rifle.loads) as the range approaches 1000 yards. While I have gotten good results using the advanced features of the AB program, at the longer ranges calibration(BC, V) is necessary. From my experience, bullet/rifle dynamics are not standardized, and need to be tested. For hunting to 1000 yards, my practice and best results are produced by bypassing the advanced settings and wind entries, and I will mentally calculate values for wind corrections based on standard wind formulas, and actual field testing… [/QUOTE]
