Any clue what is doing this to my TRG mags?

Something is beating the shit out of the lips on my TRG mags. I had noticed this happening with a used mag I bought awhile back but it had already had slight damage on it from the previous TRG owner. My TRG was brand new and when using this used mag seemed to make the problem worse. This last weekend I was at a class and this mag gave up the ghost, started having all kinds of feeding issues. So, I went and grabbed a brand new TRG mag from my back and started using it. And now it is getting the shit beat out if the lips. Nothing is hitting anything in the action, the new mag feeds fine but damn the lips are gone. Anyways I would appreciate any help anyone can give me!!!!!

Sorry for the crappy cell phone pics. I will try and get some better ones later but I think you get the idea.

One suggestion I have, guessing you are having the same problem I did as it's hard to tell in your pictures.

The TRG 22 mags are not 10-round, I found this out during a comp when forcing 10-rounds into them, thus causing feeding problems. Previous to running a TRG in a comp I would usually only load five rounds into the mags, and never had a problem. Now I only load 8-rounds max to prevent mag issues.

The first two rounds (when 10 are loaded) bend the feed lips when striping them out of the magazine with the bolt.

I would have to agree with Alpine.

When you fill the mag to capacity it pushes out on the sides. Which, pushes the tips of the feed lips in. The corner of the mag acting like a fulcrum. Load up less rounds and reload the rifle more is all I can say. I've had to do this very same thing with a number of different AR-15 mags for different calibers in the -15 platform. The wider cases mean a shallower rib to strengthen the body of the mag. The bulge and oftentimes with a full mag you won't get a bullet to release let alone hit the feed ramp the way it should.
