Fortunately, we do not have any calibre restrictions; even the 45acp is widely used by those who like to hear a big bang when hitting the falling plates.
Occasionally we organize shooting trips to Italy which as you said the 9x19mm is not allowed because it is a Military round, so we shoot mostly with 45 and 357. Some prefer to shoot their rifles, since we do not have a rifle Shooting Range yet, but we are working on it.
