[QUOTE="abinok, post: 74693, member: 16"] Sierra uses Metro for theirs. Im not sure about the others, and im not sure they all use the same one. Lost river ballistics for instance speciffically uses a different atmospheric standard. This would make their BC's appear higher than their competitors... provided you didn't know better. You could get a .6bc out of a pistol bullet if you could do your "testing and measuring" at a high enough altitude/low air pressure. smacks forehead repeatidly....gotta edit these before posting [/QUOTE]
