I read once that there was allot of experimentation using shotgun shells as casing. Is this ongoing what explosive mixtures are used in replace of gunpowder? Do special methods for barrel making and type of steal have to be used to avoid damaging the barrel with the hotter and faster burn?
Can this technique make a 1000g projectile travel at the same fps with the same kinetic energy as a .50 cal?
