Given your experience with computers you understand their limitations as well as their utility. Like you, I dismiss climate alarmist's use of computer models on the grounds that they can't model something they don't understand (don't get me started).

However, I hope I have made you aware of an alternative technique for calculating ballistic coefficients that more accurately predicts bullet trajectory in the supersonic velocity range. Likely it won't be adopted by any bullet manufacture due to the facilities needed to perform long range testing under controlled conditions. In that sense you're right, it's purely an academic exercise.
