They took a .58 barrel and filled it totally full of powder with a bullet packed at the muzzle. It fired without incident. The same test with 150 gr. charge exploded, the charge at the breach and a "short started" bullet at the muzzle.
That's why they had all those cork and felt filler wads in BP cartridges and shells! Loose BP blows stuff up.
Even the cannon charges are in "cartridges" I use plastic baggies encased in tin foil. You use the "prick" to poke a fuse hole in it before lighting. Plastic won't light afire. I do fret over static though. I used newspaper for wadding ONCE! lol We had a time stomping out all the smoldering fires!
