The best results Ive had were 195 gr Fg with a patched 15/16" steel ball and 170 gr Fg with a 3 oz patched lead ball fired out of my 1.1" bore, 17" bore length. Roughly half of Terry's blank loads, so it seems on par. For general screwing around (shooting cans, old pumpkins/watermelons, etc), I'm usually only using about 100 gr.
This brings up a few questions along the same lines, though.
I've seen lots of people refer to using 1+ oz of powder in 1" bores
when firing projectiles. Aside from the original proofing, I've only fired mine with 220 gr once (lead ball) and it kicked like a mule and made one heck of a noise. I really can't see bumping it up anywhere near 400 gr!

I was using the chart up in the reference section for 1.1" bore and I beleive ~210 grains is the upper end for 1.1".
Are there any load books/guides for .750+ bore short-barreled guns? I have several more guns/cannon in works with bores ranging from ~.750 - 1.25", but barrel(bore) lengths of only 8 - 12". What's the rule of thumb for FFg vs Fg vs Cannon powders? Obviously, if most of my powder is burning outside the barrel, I need to switch to a finer granulation starting with a reduced load. I've seen a few references to bore dia, but bore length is going to play a big part as well. Does The Complete Cannoneer go into loads and such for .750- 2" bores or does it focus on the 2 - 4" full scale stuff?
P.S. 40 gr FFg, 1/2" of papertowel wadding topped by a frozen cherry tomato is an excellent load as well. Makes for interesting "paintball" splatters on stumps.
