The .310 Cadet, also known as the .310 Greener, or the .310 Martini, is a
Current Use
After being sold by the Australian government many were converted to sporting or target rifles, often re-barreled to calibers like
Those still using the .310 Cadet have to either buy cases to reload, by Bertram Bullet Co. in Victoria, Australia, or several small independent ammunition makers in Australia and the United Kingdom. However these new .310 Cadet cases are 3-4 times as expensive as new .32-20 Winchester cases, hence shooters modify .32-20 cases, as a cheaper alternative. Modifications involve length resizing, and in most cases reducing the rim thickness. Due to the .310 using a heeled projectile, the neck thickness of the .32-20 does not have to be reamed down, after first being case length resized to 1.075" (27.3 mm). Most .310 cadet chambered rifles need to have the rim of the .32-20 case reduced from 0.065" to 0.045" (1.7 mm to 1.14 mm), to allow proper head spacing and operation of rifle. However, in the unusual instance of a lever action .32-20 fitted with a .310 barrel, the rifle will cycle better without the case rim thickness being reduced. As home reloading is the main option for the .310, many shooters play with different case length reduction of the .32-20, anywhere from 0.875'' to 1.185'' (22.23 mm to 30.10 mm).[citation needed]
