One thing with the SSAA service discipline, unless it has changed you "need" one rifle for each category you wish to shoot, plus maybe specials for specific matches (eg D Day or ANZAC) and then another one of each (for all of them) because if you have a rifle fail during a match, a substitute rifle of the same type is permitted (check local ruling of course, but the reason used to be good enough here when we had to explain every purchase)

Here a rifle held on a collectors license cannot be fired for any reason except with a "commissioners permit" for the purpose of demonstrating it for sale.
