I own one that I refinished. The ammo is refered to as the 7mm Jap round Only available from Graff and sons. Costs $1.85 a round but man is that rifle accurate!
And fun to shoot. You should have bought one.
The place selling the Araiskas by the barrel full was Potomac Arms, which closed about twenty years ago. It was the retail outlet of Interarms. I used to stop by often just to see what they were selling. They had unused SKSs for $70 each (bought a few), but I passed on the Araiska, some beautiful Martini Henrys, just like in The Man Who Would be King, a Dragunov with a long barrel and a scope, and more other rifles than I can remember. I regret most passing up batch of mint condition Red 9 Broom Handle Mausers selling for peanuts.
