I want to have some idea of how much gunpowder I can put in there, and
what is the best way to make some safe projectiles like wads of paper
or some such. I want a modest BOOM and as little destructive power as
possible.

There is a small hole on top for putting in an igniting cord.

You can probably pack it full without much worry. It is short enough that
it'll blow most excess out the muzzle.
However, the rule of thumb with black powder guns is one grain per caliber
(50cal gets 50grains of powder) and work up or down from there.
