I've noticed there are mixed opinions of Rifle Ammunition imported from Russia. I've seen reviews that say that this kind of ammunition is "too dirty", this ammunition "makes my gun jam, and it doesn't feed right", the quality of the ammunition is poor "cartridges just fell apart after it came in the mail", and more. I personally have had somewhat success shooting it through my .308 WIN CETME rifle. By my experience I'm not sure of the overall accuracy because I shot about 20 rounds in an indoor range that went up to 25 yards. The rounds did seem a bit dirtier than usual, but that could just be because of the delayed blowback the CETME has. What's everyones take on generally imported Russian ammunition here?
