magazines for 22 Grendel and improved ?

[windsage]

For the 22 Grendel I just used the 6.5 Grendel E-Lander mags that I already had. On every one of those I had to lower the front edge of the mag a bit and tweak the lips to get them to feed correctly with the 6.5. When I then tried the 22, they worked fine.
