[QUOTE="Mysticplayer, post: 109973, member: 8947"] Contact Hornady and tell what a great idea a heavy high BC amax bullets would be. I have been bugging them for years for heavy 30 and 338 bullets. There more pressure we put on them, the more likely we will see better bullets. With the Amax, remember that these bullets usually fly with a G7 drag curve. Many HP match bullets follow a G5 curve. Not too many VLD bullets are built to follow the G7 drag curve. The BC value changes dramatically depending on the actual drag curve a bullet takes. Simply, a lower G drag curve bullet with a high BC number will have higher real world drag then a high G drag function bullet with a 'lower' BC number. Just put in numbers in a ballistic program and compare. All too often G1 curves are used to generate some amazing BC values. This is not correct and real world ballistics are dissappointing. So when comparing BC values, try and find out which G function was used to generate the number. You might be very surprised at the answers. Jerry [/QUOTE]
