Obviously not a college student of the 70's...
Zig Zag is a popular rolling paper for those who roll their own... err... cartridges.
Now DD4lifeusmc is making partial cartridges, he's just rolling up the powder charge, not gluing in the ball. That works fine and is half of the work, with about 80% of the benefit. Maybe more. Not authentic to the 1800's but a darn sight better than carrying a powder measure into the field.
The real deal is to have the ball glued into the open end of a conical paper cartridge so you just ram the entire thing into the cylinder, paper, powder, ball, and all.
