OK, UpAndAtIt, if you can make cartridge cases out of those thin lipstick tubes, please do so, and post pictures. Then fire them and post pics. You are so unknowledgeable about what is required of a cartridge case in regard to containing pressure, that I tend to doubt your claimed expertise in reloading and case forming. (A bullet jacket is NOT the same thing as a cartridge case in terms of standing up to pressure.)
Making one cartridge case out of another is one thing. Making a center fire cartridge case out of a thin piece of brass or aluminum is quite another. Why do you think cartridges have that thick part at the rear? Would they bother with that if they could just use thin brass all the way around?
So, hurry up and make those cartridges out of your mom's discarded lipstick tubes and let us know how you get on. I am willing to eat crow if you do it, but I suspect you would be eating a lot of hot gas and burning powder first.
