[QUOTE="J E Custom, post: 1980098, member: 2736"] Rarely is the ballistic performance the same as advertised. The factory numbers are under optimum conditions and only account for one BC. When establishing a drop chart it is prudent to have three over the distance desired and velocities at those points. The BC can change because of performance at different velocities and should be taken into account once you have good actual drop data. then you can find the actual Bullet BC and use it in your programs for best results. Actual Bullet BC's are never the same as advertised where I hunt and shoot so I have to adjust them to match the drop chart to get good results. I also like to have a 5 to 10 mile wind at 90o to help the calculation better match the actual Bullet BC's. J E CUSTOM [/QUOTE]
