Hello,
This is my my first 6BR and really like it so far. It is a 6BR Norma (so it should be a .272 neck chamber, I bought it used). I bought 200 new brass from Lapua. The first box I opened had one piece that was formed wrong (see below). Not a big deal, it happens. I used it as a dummy cartridge now.

So I fired the majority of the 200 wirh 28.6 of H4895 and jumping 105 hybrids .025" with good accuracy and no pressure signs. Then Sized them with standard Forster FL/neck sizing die. Then loaded up 25 more of the same recipe above and went shooting. I had 3 split necks! I couldn't belive it, it is only the second firing. See below pictures.



I also loaded 15 rounds of 30.0 varget jumping 105 hybrids .025" and had no preesure signs, good accuracy, and no split necks (second firing also). So did i get a bad batch of brass? Or another stuff happens and forget about it, keep on shooting?
