You'd probably get more opinions from the Grendel forum...
But I wouldn't do it, 0.020 is too much stretch.
Remember the discussions on using a 0.136 bolt in a 0.125 cut chamber... that's only 0.011 but was dangerous.
6Arc chamber datum is 1.190; Grendel is 1.220-1.230
You're looking at 0.035 stretch, which will all come from only a portion of the brass case wall.........
