Abstract: A novel multi-slug bullet or round is provided that, through the use of flat-faced abutting end walls of successive cylindrical slugs, tightly packed above the powder charge in the cartridge casing, and appropriate fast-burning powder charge tailored to the weight of the multiple slugs, achieves multiple-hit stopping power within self-defense ranges and the like with greatly reduced penetration and thus minimal chance of lethality or collateral damage. With a single firing, multiple hits over a controlled area are achieved, materially lessening the requirement for precise aiming, reducing the amount of ammunition and the number of firings required in use, and reducing recoil, while eliminating ricochet effects.
