A rimmed, bottlenecked brass case with Berdan or Boxer primer. The 0.303 bullet was a compound design using a core of part lead and part aluminium in order to obtain the correct centre of mass, in a copper, gilding metal or GMCS jacket. The round was most usually loaded with Cordite propellant, but nitro-cellulose propellants gradually appeared; these all have the Mark number followed by the letter Z. The propellant makes no difference to the shooting, but is indicated for storage and accounting purposes. One of

the earliest small calibre rifle rounds, this appeared in 1889 and remained the standard British service round until replaced by the 7.62 × 51 mm NATO cartridge in the 1960s. A powerful round, its sole defect was its rim, which complicated the design of automatic weapons and demanded care in loading magazines. Innumerable variations in cartridge and bullet design took place during its life, but the final standard ball rounds were the Mks 7, 7Z, 8 and 8Z. The 0.303 British cartridge was adopted by the Japanese Navy in 1929 as the Type 89 to replace the 6.5 × 50SR mm round then in use, but they subsequently considered that the rimmed design might cause feeding problems and so changed to the 7.7 × 58SR mm design. They later changed again, this time to the 7.7 × 58 mm rimless cartridge, thus creating a logistics nightmare of no less than three different 7.7 mm cartridges. Compatible platforms include all British service Lee-Enfield rifles, Vickers, Maxim, and Bren machine guns, modified Browning M1919 and M2 machine guns.
