Easy Amend2 6.5 Grendel loading technique video

[Croak]

Seen a guy on the grendel Facebook page say his amend2 grendel mags swell if leavt loaded and won't fit his Anderson and colt lowers.

Have you seen an evidence of this with your mags?

Not so far, and they've been outside loaded for three range trips in 90+ degree Florida sun for several hours, and loaded when stored inside. They've only had AG and ELD-M in them, they're my "zeroing and grouping" mags, for Wolf I use my Elanders.
