That is to say that even though you have an infinite amount of ammunition at your disposal, you still need to reload your gun. And nothing is worse than going at an enemy only to find out your chamber is full. This will force Jason to stop mid-battle in order to rectify the situation. As a result, constantly hit Y as you run around to be sure your gun is reloaded. This will benefit you during unexpected battles, and ensure that if you need to reload, at least you got a full magazine off beforehand
