There were some early issues due to the front of the mag causing some rounds to hang up on it, so I dremeled the front edge down on the ones I use, take it down about 0.1-0.120, mark it off first before you get started... thread on this here somewhere. This came up by comparing some factory mags, the ones that didn't hang up had a lower front edge than the ones that did. So if you run into that, that's the fix.
I use Duramags and have never ran into issues. The same Duramag has worked for 6m ARC, 6.5 Grendel and 7.62 Russian.
