Considering the size and shape of his weapon, it wouldn't be able to hold too many shells. Maybe he can only load two shells. The first shell he loads is the explosive one in the hopes that it is strong enough to kill or injure the person he is fighting. The second one is a weaker white-shot meant to repel the enemy away or throw them off guard.
