As someone new to AR rifles and the technical details of ballistics, I would like to say that I found this entire thread very informative and also somewhat entertaining. And, isn't that what a good forum should be?

For those of you who have hashed this subject out for years, just remember that there are always new folks coming in, and thread subjects will continue to reappear over and over. That is the nature of the beast. But, it doesn't mean that the thread is useless.

Thanks everyone who posted on this thread.
