I have some questions about BC values and how velocity changes them. Lets take the 300 SMK for example. specs are .768 BC at 2300+fps. then reducing to .760 at 2300-1800 down to .750 at 1800 and below. Shouldn't the BC be higher at increased velocities? Say the 3000fps mark? I read somewhere and cant find it again so maybe I read wrong but from what I recall BC value would drop about .02 every 100fps. Is this true or is it more on bullet design/shape?
