I'm no expert on Ammo, but did you know use can use .30-30 in a 7.62x39 chamber?

The 7.62x39mm cartridge fired by the SKS is sometimes said to be roughly equivalent to the Winchester .30-30 round when used as a deer hunting round. However, the 7.62 is sometimes considered inferior to the .30-30 as a hunting cartridge, due to its historical use of relatively lightweight bullets by caliber.

At 200+ yards, a 7.62x39mm bullet, due to its more aerodynamic shape and slightly higher velocity, will provide a flatter trajectory and will retain more energy than a round nose .30-30.

Hollowpoint 7.62x39mm and 154-grain (10.0 g) soft point 7.62x39mm hunting bullets are available, but 7.62x39 hollowpoint bullets are slightly lighter than maximum grain .30-30 loadings, giving a slight edge to the heaviest .30-30 bullets over 7.62x39mm hollowpoint bullets for close-in hunting in brush amid typical Eastern United States hunting scenarios encountered while hunting for deer.

On the other hand, the 154 gr (10.0 g) soft point 7.62x39 bullets have a slight advantage over the round nose 150 gr (9.7 g) .30-30 bullets, at all ranges beyond approximately 100 yards (91 m), due to the spitzer shape of the 7.62x39. Another factor is that the most common 7.62x39 ammunition uses the harder Berdan primers, unlike the standard American boxer primers.

Some SKS rifles tend to rupture the softer primers, leading to possible mechanical fouling.

So, in short...you can use 30-30 if you can't find any 7.62x39...but use it as a last resort.
