The 30-30 Winchester calibre is intended for use on medium-sized mammals; it was developed in 1895 by John Moses Browning for the Winchester Model 94. Its non-metric name refers to its 0.30 inch calibre and original 30-grain (1.94 gram) black powder load. Modern-day loads no longer match this specification; the 30-30 calibre is now loaded with smokeless powder for optimal performance. The 30-30 Winchester case is a rimmed, gently bottlenecked type. The 30-30 was the first hunting and sport-shooting cartridge to use "smokeless" powder. The mass of the most commonly used bullets for this calibre range from 9.72 grams (150 grains) to 11.02 grams (170 grains), which can shoot large mammals such as deer and stag when conditions are good at ranges of over 100 metres. The 30-30 Winchester is a popular hunting ammunition in the United States, Canada and a large part of Europe due to its moderate power that limits the range of its bullet compared to Magnum calibres. Modern ammunition is expanding semi-armoured, usually carrying a flat nose, flat nose hollow point or round nose bullet for safe use in a tubular magazine. Winchester manufactures four optimal loads for this calibre in the standard 9.72- and 11.02-gram weights.
