I haven't had any trouble in my standard M1A, but I have seen brass from a DPMS rifle that shows a substantial swipe from the ejector on the case head from the bolt rapidly unlocking. I don't know if it was the ammo or if the rifle is just overgassed.
Interesting...makes me think that I may need to stick with the TAP especially given I shoot with a can quite frequently.
