I have been looking around to find magazines for my 6.5 Grendel and I saw where someone mentioned they use 7.62x39 magazine for that. Got me curious so I looked it up. It’s not exact, but looks like it could work. What do you think?
I mention this because my perception is that 7.62x 39 is more readily available than 6.5 Grendel. Here is what I found at MidwayUSA when looking for magazines.
