Just wondering how similar are these two loads? Are they interchangeable, in one and not the other? I have a ton of .308 brass, can I reload these to fit an SKS? Is this a stupid question?:confused:

SKS is the same caliber projectile as a .308, however the .308 is 7.62x51 and the SKS shoots a 7.62x39. So in answer to your question no, you can't. Good question though.

Weeelll.... for 7.62 it comes in many different flavors. I am going to assume you are talking about bullet diameters. The west usually used a .308" diameter bullet, as measured by the diameter of the bore. Conversely, Russian firearms tend to use a .311" bullet, as they measured 7.62mm from land-to-land in the bore, thus resulting in a slightly larger bullet. While you can shoot a .308" out of a .311" bore, the results are usually sub-par to a true .308 bore. I am unsure if its safe to fire a .311" in a .308", but I would think it would work, albeit greatly accelerate barrel wear due to increased friction. Also, I believe the British .303 used a .310" bullet, which is interchangeable with the Russian .311" for reloading. Oh, also all of those are considered 7.62mm :).

Short answer - Nope.
.308 brass is way bigger than 7.62x39 brass. It's longer and has a larger diameter. There is no way it could possibly work. I'd suggest you trade it for some reloadable brass for your SKS.

Bullets could maybe work. As was said, the SKS is usually around a .310-.311 bore. The .308 uses .308 bullets.
If your rifle is a little tight and you get just a little lucky, it's possible that you might get away with a .308 bullet. But it's just as possible that your accuracy could suck. Just have to try it and find out.
But if you're buying new bullets, I'd suggest you just lay hands on some standard .310 FMJ or SP bullets and start off with the "right" bullet to begin with.

Long story short, there's a lot of NATO and Soviet rounds that sound similar in nomenclature. But being designed independently by competing nations, they're dramatically different.

7.62x39 was designed as an assault rifle cartridge, not a full rifle cartridge. .308 (7.62x51) was designed as a full rifle cartridge. .308 is fairly close to 7.62x54R in construction, but there's still some major differences, not the least of which that 7.62x54R is a rimmed cartridge whereas .308 is rimless, and 7.62x54R is a heck of a lot hotter than .308.

Short answer, no, the brass is totally different.
