Abstract
A shotshell comprised of shot pellets of different densities and materials which provide increased effectiveness at both close and long range. Preferably the pellets are disposed in longitudinally stratified layers, with the more dense pellets located rearwardly of the pellets of lesser density. The pellets having the greater density maintain a closer pattern at long range, because they are preferably made of tungsten which has a high density and are located rearwardly, while the pellets having lesser density are preferably made of steel, describe a much wider pattern because of their lower density and forward location, and are therefore most effective at close range.
