Because sometimes in life the launcher may get damaged or other things happen and the bullet does not align with the hole and instead causes the grenade to go off at the muzzle. May also be a range difference or accuracy difference , that I do not know . The US WW1 VB cups used a bullet round , and they dropped it for the blank type.
