There are a few members here with experience in shooting competition, but not as many as you'd think, unfortunately. I'd agree, a competition oriented forum is a great place to "talk shop", but in general, this is a hunting based board, and the high level of variation between competitions might mean that there are only 1 or two shooters from a given discipline here.
I hate to say it, but if you're interested in competition, you're better off going straight to the horses mouth and joining OTHER forums that have many members focused specifically on THAT discipline than using your time here.
