[QUOTE="davewilson, post: 505631, member: 4491"] i'd like to know why there is two, or i guess seven, different drag functions. why a G1 and a G7? the B.C. number is lower on the G7. it all boils down to a B.C. number that is the function of drag. a streamlined bullet is a G7, but it's G1 B.C. is a much higher number. if we're just using a number (B.C.) to account for the bullets ability to go through the air, why can't we have one G function? the VLD bullets would have the higher number and of course the short flat base would be a lower number. i'm certain this would just be too simple and there's a good reason for it, but can anyone explain why so many G functions?
