[QUOTE="J E Custom, post: 1081508, member: 2736"] How about a Layman's explanation. The G1 BC numbers are based on a bullet model that Was used years ago and it is a standard Ogive with a flat base. The modern bullet makers like to use the G1 because it drives the BC of there "Better" shaped bullet to higher numbers. The G7 Model is modern and more closely matches the profile of the modern bullets. Even though the BC numbers go down when used, the results are more accurate. So when you see a BC in the 7s or 8s it is based on the G1 system. Bryan Litz has lots of information on the subject that is worth the read.
