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.

..33 id? About 10-30 grains and Id probably go with the smaller
amounts
At that small a bore...it will sound like a pistol shot and not much
else.
All you need to do is stuff some toilet paper in there with a rod and
pack it down. DO NOT hit it with a hammer etc etc.. and make damned
sure you take the ramrod out before firing. Put a nice 90' bend in one
end of it so you can see the damned thing and paint it a nice bright
yellow.
As for the wadding... 3/8ths-1/2" should make a nice bang.
Now for a modest Boom...use a bore at least .75" and about 25-40grs
blackpowder.
You can simply rebore the barrel bigger with a drill bit.

Really?
"Hurt" aint the word.
For Liberals, the truth is like salt to a slug.
Sunlight to a vampire.
RaidŽ to a cockroach.
Sheriff Brody to a shark
Bush to a Liberal
The truth doesn't just hurt. It's painful, like a red hot poker shoved
up their ass. Like sliding down a hundred foot razor blade using their
dick as a brake.
They HATE the truth."
