To tell which type of bb Your King should use, unscrew the inner barrel completely and look at the breech end...
If there is a small curved wire clip in place then you should use modern steel bb. If there is no clip then you should use the H&N 4.4mm copper coated lead ones. Do NOT use steel bb in the early type rifle as you will have jamms and will damage the bb probe on the end of the piston that pushes the bb up the bore.
If you need further help you can email me some good quality pictures of the rifle and especially the inner barrel/ shot tube.
Pete.
