The guy that owns this is ex-military, so I would think that he would know better....but...what if he's shooting some bad mil-surp 7.62 NATO? In a stamped aluminum receiver, that would heat it up pretty quick, no? Also, if his magazine is beat up, that may account for the feeding problems, especially if he's blasting off the rounds real quick. Shooting the NATO rounds would only heat the receiver more, cause more flux in the material, higher pressures, and potential exascerbate whatever issues he was already having. Additionally, as to the extraction issue, perhaps the higher pressure is causing the extractor to fail intermittantly as well? Anyone want to chime in?

Also, picked up a HK stamped G3 mag today, used, but in good condition for $9.50. Also, 20 rounds of .308 Venezualan FMJ, 20 rounds of British .308 FMJ, and 20 rounds of Winchester .308 FMJ. Perhaps I should pick up 20 of 7.62 NATO just to see if that's what he's doing wrong?
