I guess the Marksmanship Qualification Program
http://www.nrahq.org/education/training/marksmanship/index.asp is something the NRA came up with as a middle ground between plinking and sanctioned matches. The silhouette rifle program may be new.
I've been shooting Cowboy silhouette (smallbore and pistol cartridge) for three years. When I attended my first match I had only observed one previous match, I didn't know anyone who shot silhouette, I had never shot in any type of competition before. I just paid my money and took my chances. ;-)
I guess the real question is how to bring new shooters into the fold? What is the best way to introduce someone to silhouette shooting? Are club shoots, fun shoots and, or qualification programs the way to go?
Yes, most if not all of the matches I've been to are low pressure and welcoming. But, the new shooter needs to be there to feel welcome. How do we get them there? Is the one on one approach best? You know, "bring a friend", lend them you equipment, encourage them.
I just showed up and shot. I think most people need a little push or pull.
