Hey shooters. I've run into an issue and I wonder if anyone has some insights on it.
I'm building a 6.5 grendel on a savage 11 action (detachable mags) I have... almost finished but when I load the DBM mags, the first round seems to feed but the others nose-dive something fierce!
I'm using 7.62x39 mags b/c that's the closest model 11 mag to a grendel round, as far as I can determine.

Do I need a different mag or is there a "fix" for these to prevent the nose-dives?
Any info or solutions, thanks!
