hawkeye10, you'll be better off getting a good selection of ammo from various makers and seeing what works best. I have the same gun, and it does just fine with Wolf MC, Brown Bear, Silver Bear, and the white/black box stuff that showed up at WalMart around when Tula did.
You'll see more practical improvement in accuracy by adding an aperture at the rear of the receiver than the fanciest ammo will give you, I swapped out the rear assembly pin for a Tech Sight on mine and it made a huge difference.
A bit of advice on that SKS ... if you haven't, soak the bolt in a bath of solvent and make sure the firing pin is free to rattle about in there ... if it sticks forward things get ... ... interesting. I got mine unfired in Cosmoline, and the amount of Cosmoline that soaked out of the weapon was amazing, and it still bleeds Cosmoline from the wood when the stock gets hot.
And on the note of ... ... interesting malfunctions, I've read that softer primers will increase the likelihood of those interesting events, as the gun was designed to operate with hard commie military primers, so I don't even bother with the brass-cased stuff, more expensive and possibly more likely to slam-fire? I'll pass.
Because of that, I don't load live ammo unless the muzzle is pointed in a safe direction, get some snap-caps if you want to do drills at home, they're cheaper than a new <insert property or body part here>.
Someday I might bother to get my bolt re-worked to include the FP return spring Simonov intended to include, as I do get a very light FP mark on the rounds when chambered sometimes, even though I've never had one slam-fire on me, all it needs is an overly sensitive primer and some bad luck.

I'm rambling ... back to the subject, you're not going to outshoot that rifle without putting it on a bench and clamping it down ... don't worry about match-grade ammo until the rifle is limiting you.
Also keep in mind that your Yugo SKS was designed to eat cheap junky steel-case ammo and be fed and fed & cared for by an illiterate peasant ... you're giving it better treatment than it should have ever expected, another reason not to worry about buying the perfect ammo just yet.
They are not all made in the same factory, but some brands like say Wolf or Tula may be made in the same one. Barnul and the "Bear's" are from the same factory I believe. Now Golden Tiger if I am not mistaken was origionally slated to focus on manufactuing 5.45x39mm for the Soviet AK-74 series rifles, and since the fall of the Soviet Union has had to span out to the commercial sales and begin making 7.62x39 and so forth. I mostly see Wolf down here where I am in South Texas and I have never had an issue with them. The Bear series, and Golden Tiger series I don't run into very often so I can't give an honest opinion about them. My cousin though a few years back got his hands on some 5,000 rounds of Barnul 7.62x39mm never had one issue, so...
