US Patent 6202561: Shotshell having pellets of different densities…
US 6202561 · granted 2001-03-20
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.

Claim 1
A shotshell having longitudinally stratified layers of shot pellets having different densities by weight to provide increased effectiveness at both close and long rangecomprising: (a) a shotshell casing having a head portion and a mouth portion; (b) a primer located within said head portion; (c) a propellant located adjacent to and ahead of said primer; (d) a wad located within said casing ahead of said propellant; (e) a longitudinally stratified payload of shot pellets positioned within said mouth portion; and (f) said payload including a charge of shot pellets each of which has a lesser density by weight and a separate charge of shot pellets each of which has a greater density by weight and is disposed rearwardly of said lesser density pellets.
Claims
68 totalA shotshell having longitudinally stratified layers of shot pellets having different densities by weight to provide increased effectiveness at both close and long rangecomprising: (a) a shotshell casing having a head portion and a mouth portion; (b) a primer located within said head portion; (c) a propellant located adjacent to and ahead of said primer; (d) a wad located within said casing ahead of said propellant; (e) a longitudinally stratified payload of shot pellets positioned within said mouth portion; and (f) said payload including a charge of shot pellets each of which has a lesser density by weight and a separate charge of shot pellets each of which has a greater density by weight and is disposed rearwardly of said lesser density pellets.
