Abstract: A gunpowder substitute which is capable of also being molded into a consumable cartridge or cartridge case comprising between 50% to 75% by weight of an inorganic nitrate and between 25% to 50% by weight of an organic acid including ascorbic acid, erythorbic acid and mixtures thereof.
No idea if it works, but it sounds like fun.
It works pretty good, it's marketed as American Pioneer Powder. I recently shot a 1", 3 shot group at 100yds using TC Shocker 200gr Spire Points over 120gr. The rifle was an very inexpensive CVA Buckhorn Magnum. I was super impressed as I didn't even have to adjust the old Armsport 4x scope I'd put on it. I know one can buy ascorbic acid acid powder, all you need is to find a source of nitrates. I won't be mixing my own soon, but might consider doing so at some point in the future. Might even play with it in a 30-40 Krag with cast bullets.
