Tyler, there are a couple of threads about Ruger Rimfire matches here on DRTV. Michael Bane just did a promotional piece with Ruger, which you'll find on Ruger's web site.
There's no club or membership requirements. Also, you can shoot any make of .22lr nor just Ruger firearms either, though most people do. I would too out of respect to the sponsor.....also, if you ever hope for any "air time" with the shooting shows, I betcha they do too.
HERE'S the RUB.
There's not a published match schedule. Ruger would like to have 9 regionals and the nationals, but so far their web site only list the 2009 matches. They may not have all the sponsors/ranges lined up yet, but you think they'd at least take down the old schedule and post some match results.
If one is close by and it works out with my schedule, I'm going to try to make one. Unfortunately, Ruger really seems to like the California range they used in 2009 for the nationals. That will limit participation by east coast people. I recommend they move it on a 3 or 4 year schedule. East Coast, West Coast, Midwest, Texas.
