Next time your brother wants to mooch tell him no problem as long as he provides the components.
brass
primers
powder
bullets
Do a 60/40 split. you get 40% and he gets 60%. If I reload for friends I do an 80/20 split. But since your brother is a mooch I think 60/40 is good.
As I am unemployed myself I want to thank my wife for supporting my habit.
