It's fairly common for tannerite to be used for target shooting.
Gunpowder is commonly available for reloading.
I doubt this is common and should probably be illegal if it isn't already because it's horrible for the environment. However, blast fishing is apparently actually a thing! https://en.wikipedia.org/wiki/Blast_fishing
Note that it's not totally unregulated. If you are only an occasional user, you get a permit from the ATF for $25. Plus whatever your state/county wants.

I suspect a far greater many are injured from fireworks.
Get out of here with your ridiculous 1823 hyperbole. These explosive can be very efficient and useful when managing multiple acres.
If you're clearing multiple acres you use a track hoe and a large bulldozer. Source: the 60 acres of grown up crp we finished clearing last month.
I know the Internet wants you to think that rural life is all guns and explosions, but that's sometimes not the case. Why do you think every small town has multiple excavator companies?
Because the law is such an expensive PITA to comply with that nobody does it. People blew up rocks and stumps all the time before the mid 1970s.
Different experiences for different folks.
About once a week I get pissed off that I'm on Craigslist looking for expensive tractors and expensive attachments instead of just a drill bit and explosives all because some leftists blew up some bathrooms in the 1970s and the 1970s equivalent of people like you wrung their hands over it.
