Take it to a gun smith
You will have to specify which load.
Your gun needs to visit a gunsmith, It may be dirty, or simply have parts worn or broken. The chamber is what the shell is fired from. You load shells into the magazine.

No
Loading a pump-action shotgun is fairly simple. Open the action and hold the stock underneath your arm. Pop a shell into the action, then close the action to load your chamber. To load the magazine tube, take the next shell and push it into the action, then pin it in place using your index finger.
20-100m or so depending on the specifics of the load.
all depends on the load it varys
You will need to see a gunsmith to find out the correct answer.
The ratio of a shell type transformer does not change based on load, unless a load tap changer is used. The primary windings to secondary winding ratio is a constant. The voltage on the secondary may be dragged down if loading is heavy, specifically if the transformer has poor voltage regulation. If this is the case, you can infer the voltage on the secondary may float higher than desired under no load conditions.
A properly loaded shotgun shell slug load, yes.
