Yeah that's what I did and it seemed accurate. I was in discussion with a friend who insists on using the G7 factor because it is used for Boat Tail design bullets. when this is used the data drastically changes to unrealistic numbers. Thus it cant be correct. What drag factor is Litz using?
It's important to understand that when you change the drag function (G1, G7) that you input a numeric value that corresponds to that function. For example, a bullet that has a G1 BC of .500 will have a G7 BC closer to .256. If you enter .500 into the program, and just change the drag function to G7, the results will be 'non-physical' (BS). If you choose to use the G7 drag function, you have to know the G7 BC which is numerically different from the G1 BC.
It may be worth noting that if you pick from the JBM bullet library a bullet with (Litz) behind it, it makes no difference what drag model you pick on the setup page, as the program uses the correct G7 BC for its calculations.

Roger that. Thanks Bryan for the input. I will read on it further and you have pretty much cleared it up. I trust your numbers and always use them in the library. Thanks for what you do.
