I've been thinking about what would happen if the communists oops I meant democrats
had their way on banning lead and gun powder and just about anything else gun related like they did in England how could we improvise around this, because defending your rights with a crossbow or a taser is... not good. What I'm considering is large diameter bottleneck cartridge that holds a correct ratio of sodium hydroxide, aluminum, and diesel. The sodium hydroxide dissolves the aluminum and produces hydrogen gas pressurizing the shell with oxygen, nitrogen, and hydrogen. The shell would have either a cap or built in electrodes for spark ignition. Upon ignition the pressure and temperature generated by the O,H,N mixture would compress and auto-ignite the diesel producing a much higher net pressure and temperature vaporizing any liquid left in the shell casing and propelling the bullet down the barrel. A simpler design would consist of a shell casing with an airsoft valve for the insertion of LPG into the shell casing as the catalyst to vaporize and ignite the diesel. The large diameter bottleneck would supplement higher velocity from the lower pressure fuel. The bullet would consist of an iron or steel lathed rod dipped in a polymer or resin jacket. What do you think?
