This is a pretty cool experiment over at The Ammo Channel that proves you can use ground-up safety match heads (and a little bit of striker strip) to make your own gunpowder and primers.
When reloading components get hard to find, just head over to your friendly local restaurant supply store. Probably find something there to melt into boolits, too.
Just for the record, a 155-grain boolit moving at 365 feet per second makes about 46 foot-pounds of energy at the muzzle. So yeah, it’s on-par with your softer .25 ACP loads. Maybe with five or six matchbooks you could work up a more effective load.
Not that you should.
