psteinmayer,

It sounds like great fun, I've only shoot in practice matches for Cowboy action (SASS) and to qualify for CMP to get my first Garand. I believe I probably have all the different rifles to compete in the matches you mentioned, not sure if I'm a good enough shot to be competitive.
I'll think about it and start practicing, and of course start talking about it to the wife to get her interested in letting me go.
