[QUOTE="User4302021, post: 1677939, member: 105322"] The BC method you are referring to assumes a bullet at 2,800 fps at 2,000 ft elevation. Adjustments have to be made for speed and altitude. If you are adding .1 after 600 yards, then your bullet is not a "4", it is a"3.5". Probably because you are either at sea level, or you are only going 2,700 fps or less. [/QUOTE]
