Cartridge Hall of Fame: 25-20 Winchester Ammunition | MidwayUSA
This entry details the 25-20 Winchester cartridge, a low-power centerfire round introduced around 1895, primarily for the Winchester Model 1892 rifle. It was designed with a naming convention of bullet caliber over grains of black powder (25 caliber bullet over 20 grains) and features a rimmed, bottleneck design. While seldom used today, it remains relevant for small game and varmint hunting, with handloading offering greater flexibility in bullet weights.
