i keep my x39 lose in ammo cans after sorting them by advertised grain weight, then sorting by headstamp. Find the best consistency this way. For instance. These 4 rounds all came out fo the same sealed 1000 rd case of wolf. Can you tell which of the 4 is different. One the headstamp is different. 230+ of them were marked "wolf" the rest were barnaul. I found this to be true of monarch as well. Kind of a hodgepodge of who knows what in them boxes. I always check the head stamps of each and every round and sort accordingly due to this.
