Re: Help with ballistics please.
Sorry edge, I was not speaking directly to your comments. I agree with everything you said. I was saying that their are times when bullets become unstable and it has more to do with the whole set up instead of just the velocity. There is no myth that there is a disruption when passing into or out of the the speed of sound, and this disruption has a tendency to cause bullets to destablize. I just don't believe it happens every time no matter what. I have read to many times that certain calibers or loads are no good for 1000 yard shooting because they will go subsonic at say 900 yards. If you actually shot that caliber load combination, there is a good chance it can hold moa to 1000.
