There’s a mix that’s designed to work with rim fire and other lower-velocity stuff. It’s not as powe4ful, but is more-easily triggered.
A dumb friend put some in a chewing tobacco tin and launch it from a skeet launcher to shoot with a shotgun using bird shot. I personally would not be that close to anything I was blowing up, even with a plastic shell.

A plastic shell could be even worse, too. Using plastic and glass for shrapnel (I think ceramic as well?) is considered a war crime because they don’t show up on x-rays, which makes it very hard to find - practically impossible in the case of small glass shards.
