I have been messing with something similar in my CZ 527 - Lyman #311008 over 5.0gr. Green Dot. It shot great, going into 1.5 MOA pretty consistantly. But the problem is the pressure is so low that the cases shorten, increasing headspace. After a couple of reloads they wouldn't fire anymore and had to be opened up, resized, and fireformed with full loads. The brass is very thin and shoulder easily set back. So when I want 32-20 loads I use my 32-20 and keep the 7.62X39 for full or nearly full loads. BTW, this is about the max velocity you'll want to run a plain base bullet - 1500 fps or so. Beyond that it's really tough to get any accuracy and most will lead the bore. For full loads use the Lee C-312-155-2R and book jacketed loads and you'll be happy. A full load of 1680 or 2200 works great in the SKS as long as the bore is cleaned of all jacket fouling first.
