Here are the details of a ceremonial cannon burst at a youth camp in 2003. The story is one of error on top of error leading to the death of a 16 year old camp counselor.

Yeah, these folks don't seem to understand that true cannons are huge pieces of iron.  Or that the powder used in them is closer to the original Chinese recipe of coal, saltpeter, and sulfur, than to modern Black Powder intended for use in rifles, or pistols.

I've seen photos of modern Howitzers, banana peeled.  Resulting in the deaths of several of the crew members, and injuring others, not anywhere near the gun.  All because someone fluffed up setting a fuse, or used the wrong powder charge.

I'm my experience with explosives, black powder is one of the most dangerous. It's dangerous for a variety of reasons, chief among them being the fact that people don't respect it. They think of it as "just fireworks" or what they use in their muzzle loaders.

Real black powder can generate enough static just by swishing around to initiate itself. There are different grades with different pressure levels as well, and most don't know the difference.

We had a guy come into the gun store one day. He wanted to buy a hundred pounds of black powder. We didn't have any, much less a hi Fred pounds, but we asked him why. He wanted to make a cannon, and was planning on using (i swear I'm not making this up) ten pounds per shot.

He was interesting to talk to. I'll leave it at that.

If you ever sell some to him, give EMS a head's up call... "Just thought y'all'd like to know..."

Ten pounds per shot?    :scrutiny     Seems to me that would put him somewhere in the range of a four inch deck gun, no?    :panic

Well, let's see, charge 5 white bag was about 40 lbs.  The highest being charge 8, at about 60 lbs.  But you've gotta figure, that was in an M110 Howitzer, weighing in at a robust 36k lbs.  Most of which was in the tube.  The breach block alone was about 400, the thickness of the walls @ the chamber was 6 in.  And all that to put a 200+ lb. round 26 mi. down range.

So yeah, 10 lbs. sounds about right...  To blow yourself into the next county, at least.  :facepalm

I used to crew a Grasshopper 3 pounder during re-enactments as part of my old job. You quite simply just didn't screw around with the cannon. Fun as hell to shoot but took a lot of respect.
