[QUOTE="Kevin Thomas, post: 262444, member: 15748"] Hi Sandman, Just to make sure that you're thoroughly gang-answered by the Berger crew here, let me add a bit to Bryan's comments. Sierra uses multiple BC, velocity "break-points" in an attempt to "force fit" what the bullet does in the real world to what the G1 model will actually accomdate. The bottom line here is that when you use a drag model to work trajectories for a bullet that differs greatly from the standard for that model, problems arise. Since the G1 is the single drag model that is used for virtually all US commercial markets (to reduce confusion for shooters trying to compare, say, a FN design to a VLD design, where the flat nose could concieveably show a much higher BC; different drag models for each), Sierra was just trying to stay consistent with the industry norm, and make the best of a bad situation. The best solution, as Bryan described, is to use the appropriate drag model for the bullet you're working with. Just another pebble for the pile, Kevin Thomas Berger Bullets [/QUOTE]
