Projectiles weighed from for the 25 cm, to for the 35 cm, and for the 45 cm model. Accuracy, velocity, and range were all considered to be poor. The early projectiles also had poor aerodynamics, so later projectiles became more conical in shape. Due to poor aerodynamics, the projectiles sometimes fell on their side instead of their noses so timed fuses were used instead of impact fuses. The slow-moving projectiles were given the nickname of "coal buckets" by the French.
