I bought two of the Duramag 26 round and a 20 round mag. I loaded all 3 and with no problems. After 3 weeks of them sitting fully loaded I got to shoot the 20 round mag. I only shot 8 rounds but had no problems, no need to adjust or polish feed lips. I did not get to try the 26 round mags, it was about 100 degrees and 100% humidity. Earlier I was mowing my trails at the Club and the 100 yard shooting range so I was in no shape for serious shooting.. However the 12 inch GM 1/7.5 monster barrel shot the Gunner ammo nicely at 50 yards and 100 yards. The Duramags like my other CPD 5 and 10 round 6.5 Grendel mags seem to be just fine.
