[QUOTE="budlight, post: 542340, member: 2939"] What your asking does not matter. I chrono measure @ 20 feet to get a more realistic speed. Bullets don't have a static BC. It is dynamic (always changing) Some manufactures give the change in BC within velocity ranges. Example is a .560 BC at 2800 + FPS At 2400 FPS the BC is only .530 and at 2000 fps it is now only .500. So for a long shot you have to get an average BC because of the decreasing BC I think Sierra bullets lists velocity changes BC's for their bullets. I've often wondered about aerodynamic changes with a 6 groove barrel over a 3 groove. That is why range BC calculating with real life bullet drop actually shows true projectile BC. Some manufactures list highly overrated BC's for their VLD bullets just to make a sale and the bullets never live up to advertised BC in the field [/QUOTE]
