A projectile firing weapon (10) for firing artillery rounds (30) from a barrel assembly (11) utilises rounds having a projectile (31) and an associated bore seal (32) which is radially expanded by relative axial displacement between the projectile and the bore seal. The barrel assembly (11) provides a barrel bore (13), a barrel chamber (14) for the round to be fired and an associated breech chamber (15) for the next round to be fired. A propellant chamber (17) is formed between the barrel chamber (14) and the breech chamber (15). The breeched round (30) provides the closure for the barrel chamber (14) and after firing is advanced into the barrel chamber (17) by the next round introduced to the breech chamber (15). Liquid propellant may be injected to the propellant chamber (17) to facilitate rapid firing.
