[QUOTE="Mikecr, post: 2577287, member: 1521"] No it's not correct. BC = Sectional Density/Form Factor Sellier & Bellot should have run this with any modern ballistic calculator to see that their posted G1 formula does not represent BC. What it likely leads too is total drag, which is divided by a G1 drag coefficient at velocity -for G1 Form Factor. And simply defining a result at 400m asl, at 100m, is not the same as prediction otherwise. [/QUOTE]
