OK fellow cannoneers, here are the questions. How many grains of FFFG is safe to fire in my 20mm cannon? The cannon weighs 25 pounds. I will be using newspaper for wadding. What are the best techniques to incorporate to obtain the maximum "boom" for my buck? Any imput is appreciated. Thanks.

Grains? Hell we just pore till it looks right and then use a wine cork with a little wad. Ours is home made from a 3" Dia. Stainless Steel High pressure steam pipe with a 7/8" (Strait bore) No expansion chamber.

I do remember you would get about 3 Healthy shots to a pound of Pyrodex. and It could be heard though out the Puget sound in WA.

All I am trying to say is be careful using FFFg powder in a 20 mm cannon. If FFFg is all you have start with 40 grains and work upwards till yo get the noise you want but don't go much past 70 grains due to excessive pressure since you are paper wadding it.
Dixie Gun Works catalogs have all the info as to BP that a person would ever want to know. It is worth the $7 or $8 it costs. It has a lot of info on shot sizes, colt guns, and BP cartridge guns as well. Just my 2 cents worth.

We had an idiot here in Bradford last week who bought one at a garage sale and loaded it with rifle powder, yes it blew up , and half of it went clear thru his gut, he is still in very critical condition!!!! The other half went thru the side of his neighbors house!

The plaster projectiles make it easy to see hits at long range.
It sounds wicked when it goes off.
I can just imagine being an infantryman in days past, charging down cannon loaded with grape shot. Glad I wasn't there.
