There are many kinds of advanced marksmanship training. Some is precision oriented, some speed oriented, and a precious few are staying alive oriented.
I attended a class this weekend in West Virginia that was one of the "stay alive" kinds of classes. I would recommend that you take a look at these classes.

By the way, I am one person who had some gravity issues this weekend (as my face can attest). I am also sitting here and feeling like I just finished the first day of Football practice. That's not a bad feeling for someone my age.
I will be happy to answer any questions you might have.
