I did a good bit of testing with Magpul 30 rd's and Grendel. For me they have been very reliable loaded 5-6, get hard to insert in the mag well up to 10, and get unreliable in the 10-15 round range. That's due to the thickness of the magpul walls. I have not tested, but my suspicion is that an alloy or steel mag would allow a bit more rounds, but you are really going the long way around to avoid Grendel mags.
Not recommending magpul as an alternative, just confirm the reliability (and not). It's all about the case taper and the fact that the magpul & 5.56 mags do not allow a proper double stack mag. I've posted diagrams on this in the past.
Between my brother and I we have 15-20 cprod 25 round (30 rnd format) grendel mags, and 3 17rd bought over a 2-3 year period. Just never had an issue. All have been reliable. About my biggest complaint is that a few were snug in billet receivers, about the same as a magpul is.
Hopefully ASC/Cprod will pick back up. If not, someone else will I suspect.
6.8 Barret mags are pretty, but if that was what it took to shoot grendel I'd not be fooling with it.
