The Martini Cadet is a centrefire single-shot cadet rifle produced in the United Kingdom by BSA and W.W. Greener for the use of Australian military Cadets..Digger History Although considered a miniature version of the Martini–Henry, the internal mechanism was redesigned by Auguste Francotte to permit removal from the receiver as a single unit. Chambered for the .310 Cadet cartridge (aka: .310 Greener), it was used from 1891 to 1955. They were also sold to the public thereafter, as the BSA No.4, 4a, 4b and 5 in other calibres like the .297/230 and .22 rimfire. The rifles will often chamber the similarly sized .32-20 Winchester and fire with some accuracy. However the 32/20 is actually 0.312 cal and the 310 is 0.323 cal. Due to this 10 thousandths difference the accuracy of a .32/20 round cannot be guaranteed.Cartridges of The World by Frank C. Barnes
After being sold by the Australian government many were converted to sporting or target rifles, often re-barrelled to calibres like .22 Hornet, .218 Bee, .25-20 Winchester, .222 Rimmed, .357 Magnum and others to .22 rimfire by gun makers like Sportco.Rifleman UK
