Charging the barrel takes many forms. Some put pellets down the barrel and drop a projectile on top of it. Others such as yourself load from speed loaders. Some have numerous pre measured vials of powder that they pour down the barrel. Then like me, some simply pour powder from a horn or container into a powder measure which obtains them a set powder charge and from there they pour that into the barrel.

Just remember, never pour powder straight from a powder horn or jug into a barrel. And the old method of holding a ball in the palm of your had and then pouring powder to surround the ball, again.. not recommended.
