I'm actually toying with the idea from another forum. I read a tutorial on how to make paper cartridges by just using FFF and cream of wheat. Just pack this cartridge into the cylinder and load a ball on top of it. Thus eliminating the need for a wad or lube.
I've made some. It is time consuming but takes less time to load when you wanna shoot. I make mine with tea bags and glue the paper to the ball and load everything at once. No need for filler with 30 grs. or more of powder.
