Can a small number of Grendel rounds feed reliably from a Magpul magazine?
Based on my testing with a 30 round pmag, yes. In my rifle, AA barrel / bolt. AA upper receiver. LMT lower. 5 was 100 percent reliable.
10 was reliable but tight in the magwell due to bulging. (Body as much as the lips)
15 was too bulged, and would malfunction.
I'm not sure I'd trust them for storage. But for range use they appear to be fine.
This is neither hard nor expensive to test.

Did not measure, but 123 AMAX's at my normal COAL had plenty of clearance. I suspect if you are using VLSD's you may hit a snag
Quote:Would a cut down Magpul magazine weigh about the same or less than a C-products 10 round magazine?
Negligible difference, especially if it was cut down. You really worrying about mag weight???
Quote:I would like to cut some of the 20s down and make some for hunting.
I live in California so I have the 10 or less problem with new magazines anyway.
Not real sure how you'd cut down 30's. I've not tried 20's with Grendel. But you could sure block a 30. Maybe cut & solvent weld it?
