Here in the eastern Region NBRSA, Hobie Bond is our Regional Director. Although I haven't shot in a few years (work schedule sucks), I still get emails about every month from either Hobie, or clubs in our area that areholding matches. It may very well be the NBRSA's job to put out match schedules, and reports, but as a shooter you need to gather this info for yourself as well.
In Michigan we have a few ranges, as for NBRSA, we have Holton, and WWCCA. We also have Harrison, now non registered, and Iosco's 2 IBS registered Ranges.
Durring the winter months Ranges in our area set their schedules and either mail them to shooters, or e-mail them, or post them on their websites. I gather this info and put together a calendar that lists the matches that are important to me for various reasons, whether it be to attend, or to make sure I don't schedule against Larger matches. My calandar works for me and may not work for you either because of different shooting priorities, or different location, but here is an example.
You get out of it what you put into it!
