For all of you fluff nuts out there. How do knight paladins reload? They surely don't carry enough rounds in their battle cannon mount to last a whole battle. The models ( which I acknowledge are not always accurate) armature doesn't seem thick enough to have the rounds feed through the top. I have read mechaniucm but not the codex. I can't recall if mechaniucm described reloading their battle cannon in battle. Thnx!
