Sounds like tons of fun! Enjoy it!I bought a box-full of the rolled paper reenactor tubes on ebay, and have enough for my forever.
We use them in the Texas Army. Some events allow pouring powder and then ramming the paper tube, or else we drop the empty tubes on the ground.
You can fill the tubes with your own powder loads at home, and you're ready for the field.
For our salutes and battle reenactments, I like about 100 grains of 2F or 3F, and gets LOTS of smoke and flame.
It looks GLORIOUS!
