    I shot 2 boxes of ammo through my AR308 this Saturday, and Sunday morning when I went to clean them, the .308's nickle boron bolt and carrier were COVERED in the worst green corrosion I have ever seen. Worse than when I shot corrosive soviet era ammo through my milsurps and waited a week to clean. One box was IMI match and the other box was GG&G match. This corrosion was soo bad nothing I had would take it off, so I had to polish it off with a dremel and chrome polish.

    Has anyone else had this experience in the past?
     
    I did. It had 20 rounds of Federal GMM put through it a few months prior. I ALWAYS clean my guns that day or the very next day, so between then and now, nothing else ran through that gun. No way I put a gun away dirty. It's been a wall hanger due to the weather here.
     
    extremely odd results from your shooting experience. I would locate your round here and try and determine which ammo was the culprit if either, as stated my experience has been the GG&G is very good ammo.

    Oh I wouldn't say it's bad ammo, just that it tends to leave a greenish stain on stuff if not cleaned promptly. accuracy and reliability wise it leaves nothing to complain about.
     
    This is the corrosion. The flash kind of drown out how green this stuff was. It was a bright, deep mint green, and it was ON there. This nickel boron BCG was super nice and bright. (lantacs coatings are always so nice) It was brand new. EVERY bit of that green and brown crap was on there, hard. Hoppes, shooters choice, KG powder solvent, and 90% isopropyl wouldn't touch this stuff. I had to put Mother's chrome polish on a felt wheel and dremel it off. Every square inch. This was 20 rounds of ammo, and about 20 hours of sitting before cleaning.
    Even the issue russian stuff that I fire through my AK74 and then sat for a few days wasn't this stubborn. Never seen anything like this.

    I have a nitrided Lantac E-BCG and no issues with IMI Razor 175gr. I've put about at least 60rds through it in 2 weeks without any cleaning and everything looks fine.
     
    Only issue I ever had with IMI 175 match was the accuracy going to shit at 800 yards and beyond. This happened with multiple shooters in multiple rifles. Other than that it was okay...
     
    Thanks for the replies thus far guys. Anyone else?
    I have 500 rounds of GG&G .308 and my friend and I both shoot it in our rifles. I have several in this caliber and my friend has a POF Revolution. We have been shooting it for almost a year and neither of us have experienced what you described. Our rifles are top of the line, but I don't know if our bolt carrier groups have a coating that would prevent this problem. Either way,
    the GG&G is my go to range ammo, and could be defense ammo in a pinch.
