Range report update
If you want to bring the worst in your gun get a NORINCO ammo

I just got a case of non-corrosive 7.62 and start having a lot of issues with the rifle. But let me say first that heavy buffer while reducing felt recoil a little generates a lot of feeding and extraction problems with normal ammo. Back to stock buffer - and rifle runs flawlessly. Now, back to Norinco ammo.
1. Copper washed finish is very rough and not uniform. I was experiencing a lot of feeding problems with otherwise fine with other ammo (Romanian surplus) XCR mags. You probably already know about dimples issues with those mags and problem they generate. After removing dimples and lowering the front edge with Dremel feeding problems have gone. Moded mag feeds Norinco and even better lacquered ammo. I am going to mod the rest of my mags to make sure that rifle eats everything that I throw in it.
2. Stuck casing in the chamber. Norinco casing expands a lot. Combined with rough surface of the casing and generally dirty ammo in general in almost glues fired casing inside the chamber. I've had some FTE cases and the worst was completely stuck case that only budged with cleaning rod tapping. Luckily,extractor was undamaged.
3. Ammo is dirty. It's more dirtier than Romanian surplus. I would say 2-3 times. I've fired about 600 rounds of Romanian surplus at first time and receiver, bolt carrier and bolt were dirty, but nothing extraordinary. Today, after only 200 rounds of Norinco it was so filthy!
4. On the other hand, I've had no FTF with Norinco and 4 with Romanian surplus today.
In short, I would not recommend Norinco ammo to use with this rifle. I am sure that it will work well in SKS, AK and VZ.
I still don't have an accuracy report since I was dealing with those issues. But after quick zeroing at 50 and 100 I've managed to hit the metal plate at 300 a lot of times from standing with support and kneeling positions with Elcan Specter DR 1-4x.
More to come later
