Shotshell
From the 19th through the 20th, and now the 21st century, Winchester has led the industry in ground-breaking developments in shotshell loads and components.
In 1997, Winchester introduced the most technologically-advanced shotshells in history - Supreme® shotshells. With exciting new Supreme offerings in 2000, Winchester is continuing a shotshell manufacturing pedigree of quality and innovation that extends back to 1886.
