Before there was a shotgun, there was this blunderbuss, which has a flared barrel, sort of like a horn or bell, to spread the scattershot. It's an 18th-century flintlock with only one shot, but the upside for the shooter is that he didn't need to aim. "The huge barrel was loaded with buckshot, nails or whatever was available, and the extra-wide muzzle assured a wide dispersion of great pain and destruction," wrote Gerry and Janet Souter in "Guns of Outlaws."
