 The .303 British is one of the few (along with the .22 Hornet, .30-30 Winchester, and 7.62×54mmR) bottlenecked, rimmed centerfire rifle cartridges still in common use today.Most of the bottleneck rimmed cartridges of the late 1880s and 1890s fell into disuse by the end of the First World War.Commercial ammunition for weapons chambered in .303 British is readily available, as the cartridge is still manufactured by major producers such as Remington, Federal, Winchester, Sellier & Bellot, Denel-PMP, Prvi Partizan and Wolf.
