Saw one at the gunshow here in Edmonton the other weekend.
Personally, I'm not interested. The Nork bolt-actions are just appalling. The stocks are made out of some sort of stained softwood - REALLY soft, like balsa almost. Metalwork is miserable, finish is bad and nothing really fits together all that well. Accuracy is crap (guys who've owned these say they're no better accuracy-wise than an SKS). I've found that bedding most nork rifles results in a massive accuracy boost. And, oddly, the triggers on most norks I've shot have been excellent.
But, I built a .308-39 bolt rifle out of a Stevens 200. The barrel was originally a Winchester 70 30-06 10" twist that had been set back and chambered with a 7.62x39 reamer with a 308 pilot. This thing is STUPID accurate with 110 VMAX bullets, and handles surplus .311 dia bullets with no ill effects. Though I should note that the Stevens action is built to handle cartridges producing at least 10,000 more PSI than the SKS is designed to handle.
While this gun puts 5 VMAX bullets into a single 1/2" hole at 100 yards, the czech surplus doesn't do much better than 4".
The conversion isn't particularly expensive. The cost of the Stevens 200, minus the resale value of the barrel, plus the cost of a new barrel and a PPC extractor (or PPC bolt head if you want extraction AND ejection). Works out to ~$400 give or take
