Yes. You will get the better data woth G7 than G1 with most current boat tail bullets. With flat base, Spitzers, G1 will work just fine. Another thing to factor here is that BC changes in flight. And it changes with different velocity. It really isn't a fixed value, though it is usually stated as such in the specs of the bullets. Best thing to do if you want the best data is to use the trajectory validation tool in your app. When youbuse the tool, and you input your actual drops that you see at extended ranges, the app will ask you of you want to modify the BC to back-calculate, or if you want to modify the velocity to back-calculate. If you use a very reliable, very accurate means of measuring bullet speed (magneto or labradar). Then when you get to this point in the app, you would tell it to recalculate by changing the BC. Once that is done, you dial to the new drop value Tha the app provides, based on the adjusted BC, and if it provides you with a good hit elevation, then you tell the app to accept the modified BC. If you do this very carefully at varying distances, you will essentially create you own custom drag model, specific to your rifle, your bullet, your velocity, your twist, in your area.
