From the picture, the cartridges use shotgun primers, shotgun powder, and homemade cases and bullets.

It appears the cartridge cases, possibly of aluminum, were improvised from the individual cells found inside the common 9-volt transistor radio battery. They are also sometimes used as the body for homemade blasting caps, as used on reloaded hand grenade fuzes.

You have a better eye than I do. I though they were just aluminium tubes.

Thanks for the info.

Do they use bullseye for the filler?
