Hey, I just picked up a box of 1200 of the 2014 production Norinco "white box" 7.62x39 non-corrosive ammo 122gr. What can you guys tell me about this ammo accuracy, reliability and cleanliness wise? I bought it to shoot in my Russian SKS and wanted to avoid corrosive stuff. What type of cleaning will I have to perform after shooting this stuff? Is it steel shells and lead FMJ bullets, are the bullets coated with anything?
