Savage said it was bad mags and sent me a new one, which was an SXT-same exact thing! I called my local gunsmith Holcomb Kearns in Tallassee, Al and he advised, as y'all did above-feed lips. feed lips, feed lips. I had 3 mags, so I bent and pried on one, filed a little on another and polished with a Dremel Tool on the third. Experienced the mag emptying burst of joy a couple times on the first, got an improvement on the 2nd, and was real pleased with the 3rd. Readjusted #1 until it kept the rounds in, then polished. Polished what I did on #2, and when it was all said and done-I now have 3 mags that feed a hell of a lot better than before. The polishing of the feed lips in front seemed to help the most, smoothing the transition into the chamber with just enough of front angle change to make the difference.
