[QUOTE="Indy, post: 21526, member: 345"] Remember that some published BSs are not quite accurate, and mostly overstated. This is because they are determined mathematically form the shape of the bullet, not by firing it and measuring the drop in velociey at different ranges. Also, the BC changes with vbelocity. Some are understated. for instance, Sierra says the BC of their 80 grain .224 Match King is .424, but some knowledgeable people have measured it and gotten values up to .484. [/QUOTE]
