The CMPrules list two different courses of fire for these "games". Which one is at the discretion of the match director. Read the bulletin when it becomes available April 1 to find out which course will be used this year at Perry. It will probably be the "A" version, 35 shots, but they could decide to use the "B" course, 55 shots.
The rulebook can be found at the web page linked in my earlier post.
