I assume you are a member. If so, go to their website and log in. Then on the top header you will see events. Click on that and the 2021 National Championship (date not updated yet) will be in the list. Click on that and in the body of the message will be a link to the shoot program which lists every match available and target shot. For the most part the 6 bulls (7 & 8 ring) and the 100 yd targets (7 & 8 rings) constitute many of the matches. Also, the Charlie Haffner championship has become very popular....The Haffner squirrel, crow, combination (we always called it the "nightmare"), standing groundhog, fox, and buffalo.
There are four targets generally used in the as issued musket. These are the 3-bull 100 yd target, 7-ring 100 yd target, 200 yd target, and the NRA 300-meter international target.
I don't shoot the smooth bore so I'm not too familiar with them but in the offhand aggregates they do offer them in both rear sight and no rear sight classes. Many of the smooth bore matches are shot up in the primitive area.
There are many more targets used but not offered in the store.
Hope this helps a little.
