LTCetme: You are in a perfect position to associate with the U.S.Navy Atl Fleet Shooting Team (www.usnst.org) which holds matches every May at Dam Neck. This gets you in with the practical end of shooting. When you say Ballistics, you should know that there are three siblings in this family (Interior, Exterior,and Terminal).The first deals with the primer to the muzzle, the second from muzzle to impact, and the last with impact results. People have spent their entire lives with only one or a bit of a second. Myself, I have 80% interior and 20% exterior (almost no terminal studies other than anecdotal from others in related fields). The USN Shooting Team has a listing of related sites on their web site. As a Service member, you might contact U.S.Army, Redstone Arsenal, Huntsville, AL and ask for their correspondance course catalog with a specific request for ballistic subjects.
