Probably a stupid question, but better than a stupid result.

I got some .430 round ball. Loaded some .44mag.

Target looked like I was shooting BIG buckshot.

Soft balls leaded the barrel something fierce.

They are awesome from a wrist rocket. Rabbits hate them.

This is how pipe bonbs are made. The only difference is the source of the ignition. Do not attempt!!! If you insist on trying, please use an inexpensive firearm and a looooooong lanyard to pull the trigger. Also, I would attempt this from behind substantial cover to limit potential personal damage from metal fragments.
