Good info, but my question then is if the rim of a Grendel Case it thicker than a 7.62x39, would it require you to modify the extractor to catch the outside edge of the case? It can't just be the depth of the head-space, it seems as if the distance from the bolt face to the edge of the extractor needs to be more. I don't have a 7.62x39 case to measure but the Grendel is measuring .054 with my calipers. So if the HS is .135-.054 that leaves .081 on the lip of the extractor. Or do you mill off .010 off the standard 7.62x39 extractor???
Does this make sense???
