Draco wondered how useful the weapons might be against the Death Eaters – the bullets could of course be deflected by a shield charm, but it was possible the enemy would not realise what the guns were and be ignorant enough that they didn't raise shield charms. Also, the bullets appeared to travel very fast, faster than spells, Draco thought as he lurched further back, holding in whimpers of pain at the movement as armed soldiers charged into the room in their strange white full-body suits and black gas masks. A wizard might not be able to raise a shield charm in time to block the bullet.
