Considering the purchase of a case of Federal .308 175 gr GMM. After having read postings (dated from 2009) on other forums, there seemed to be issues with excessive copper fouling from this loading. There were also more than a few stating that copper "Shavings" were noticable on the bullet at the case crimp line, like the bullet and brass fit was too tight when being seated. Is this still the case with current lots of this ammo and / or has anyone else noticed the aboved noted issues??? Thanks for ANY input.
