For my four stages:
21+ Rifle(revised count 7/12)
16 Pistol
1 6lbr. shell w/fuse (I will supply these for all)
Let me mention that one of my stages calls for just six pistol rounds, plus the 6lbr. shell, so everyone will need a sidearm for that stage regardless of which category you're shooting in.
In addition, all rifle rounds are loaded one round at a time, so all will become, in effect, single shot rifles.
