The Swiss German name for early experimental propellant which means: "shooting cotton" or common guncotton. We are experiencing a shortage of propellants used to reload our cartridges. The common rifle, pistol and shotgun propellants have become very expensive. Companies have tripled and quadrupled their prices. Why???? Was watching several videos of the manufacturing of gun cotton. It is quite simple. The U-tubers use common Stump Remover like Spectracide Stump Remover (Potassium Nitrate) and Zep Drain Cleaner (sulphuric acid) to treat common cotton balls to make gun cotton. It is interesting to watch. Gun Cotton was discovered by a Swiss Professor at the University of Basil, Switzerland in 1846. Professor Schonbein found the stuff is 4X's more powerful than black powder. Later it was found that the nitro cellulose could be dissolved, extruded and cut into flakes, rods and spheres that could be used for driving projectiles. It is my belief that a few very enterprising individuals will start manufacturing smokeless powders because of this shortage. Usually government hinders manufacturing in this country. Obama turned the EPA into one of the biggest inhibiters of modern manufacturing in this country. We do not mine lead or process it in this country. Batteries have become very expensive. Our lead is imported. My hobby is recreational shooting. Supplies of primers, powder, and lead have dwindled. Prices have gone up. Just food for thought. Wanted to share with my "Boolit Buddies" !!
