Rossi has a 7.62x39 available. I have read similar things about their gun, where some users have had problems with primers and failure to fire, why other's seem to be fine. Knowing that milspec ammo is out there, and their customers would likely use it, you would think that companies would beef up the necessary components to ensure reliable ignition. IF the Chinese can make an SKS that is as reliable as the sun rising with this ammo, a simple single shot ought to be no problem.
