The Smokeless Powder Cartridge era is generally considered post-1899. This will include Rimfire, and Centerfires, although Pinfires were used in Central and South America well into the 20th Century they will only be included in the Black Powder Section of this Web Site. Smokeless Powder was the next giant step in the evolution of firearms. It allowed much higher chamber pressures thus more velocity and improved both range and accuracy, in some cases, many times that of Black Powder.
