I am by no means the expert. There are several competitions other than the Grand Nationals, I'm not aware of all of them but there are several. If you are on Facebook there is a group there that is a good source of info. The ones I can think of are: Keystone Classic, Buckeye Challenge, Mountain State Championship, Virginia Open, Grand Nationals, Southeastern Championship/Dixie Deer Classic and the Great Lakes Open. There is another one in Mississippi, but I know nothing about it. I'm sure there are others, this is by no means a complete list. As far as I know all of these are open to any call maker.
