Hi, complete novice to reloading (i have never in my life even fired a firearm i just like reading about stuff). I am interested in self-sufficiency and the idea of a completely self-produced cartridge. From what I can tell, the two hardest parts would be the primer and the powder (i am NOT making my own brass).
Black powder is very easy to make, but smokeless propellants are more finicky. I want to know how viable using homemade guncotton(flash cotton, nitrocellulose, flash paper or whatever kind of nitrated cellulose is available) would be possible for reloading to modern cartridge standards. I specifically am interested in the use of flash cotton for .308, 9mm, and/or 12ga.
I know the basics of how faster vs slower powders affect burn rate and chamber pressure so i understand that for larger rifle and shotgun cartridges the chamber pressure might be too high to be used safely. I mostly just want to know if anyone has any advice about guncotton reloading like manuals or youtube videos.
tl;dr, guncotton reloading manuals/videos/experience/advice
edit: i looked into your guys advice and realized the surface area issue. i will NOT be doing this because i value my life
