Brass gash, should I shoot it?

So I was tumbling some .338 Lapua brass and while adding them I noticed there was no movement in one area. Apparently the stars aligned and between the outer wall and the central cone/stem two pieces wedged in there so that the mouth of one dug into the other. The gash is a little over .150" long and maybe .005" at the deepest point, a little under 3/4" from the case head. It's Lapua brand brass and I know the cartridge was designed to have thick walls. Anyone know what the wall thickness is at the bottom half of the case? Should I shoot it or not?

That's the way I'm leaning. I found this picture of a sectioned piece. The neck is typically around .015" so based on that picture the wall should be around .040"±. It will be interesting to see if the brass flows enough for it to disappear after one firing. I've had marks on necks and shoulders flow out, but nothing this far back.

That gash is nothing to be concerned about, go ahead and reload it up again.
