[QUOTE="Wedgy, post: 2224978, member: 64108"] Keep in mind that BC is an average and varies with speed, higher speeds = higher BC, so the stated BC is calculated at "normal" velocities so at 4,000 fps it will be higher. As an example Sierra gives their BC's at different velocities. This is for the .308 230 grain SMK; .800 @1880 fps and above .780 between 1600 and 1880 fps .740 @ 1600 and below [/QUOTE]
