The M1891, 91/30, M38, M91/56, M44, and all the Finnish variants all fire the 7.62 x 54mm Rimmed cartridge. Usually known as 7.62x54R, or 7.62 Russian.
The only Mosin Nagant rifles which fire a different cartridge are the M1891 rifles captured by the Austro-Hungarian Empire during the First World War. These were converted to fire the 7.92x57 cartridge, and are extremely rare.

You probably mean the AK-47. But the Ak-47 was not a sub-machine gun, it is an assault rifle. SMG's shoot pistol rounds such as 9x19mm Luger. Assault rifles fire scaled down versions of full power rifle rounds. The AK-47 for example shoots 7.62x39mm which is a scaled down version of the Russian 7.62x54mm rifle round used in the Mosin Nagant rifle.
None: You may buy 7.62x54R ammunition in the US but it is not made in the US. Try Midway: http://www.midwayusa.com/viewproduct/?productnumber=580234 or another supply house. Ed
The Mausers rifles, such as the Kar98K, fire this round.
, This is a very unsafe practice. While there are adapters made which allow one to fire pistol .32 caliber ammunition singly through the Mosin-Nagant, there is no rifle cartridge which will interchange with the 7.62x54R. Please do not try it. Josh Smith Smith-Sights.com
