4H Comp Equipment Questions

I was wondering what type gun do the 9 year olds use for 4H. Is it semi auto or bolt action? Does it matter if its magazine fed or tube fed? I need info on equipment they need so we can start looking for a rifle for Miss Hammer so she can start practicing with it and feeling comfortable with it. Keep in mind that it’s going to have to be a left handed gun or be able to be modified to accommodate a young left handed shooter.

i'll have to look when i get home, still have all my old rule books, but i honestly dont know that 9 yr olds shoot .22 in 4h
