The real challenge is to put it together without opening the box...
Yes, the grey small cylinders holds gunpowder and bullets. His pistol is muzzleloaded, so after firing his one and only shot, he must measure up the correct amount of gunpowder, insert it in the gun trough the muzzle, followed by a bullet, and then a piece of cloth or paper to stop it from falling out, and use the loadingstick to press it all together, and then pull back, prepare and load the cock and "balcony" *phew*
Try to do this when someone are shooting at you in the heat of battle!!!
Therefore the right amount of powder, bullet and paper is prepared and ready in grey easy-access cylinders. Gives the pistolholder a good and somewhat fast firing rate
