well I ordered some nosler brass for my 22-250 this summer and I loaded them up to take back to west texas with me, well the problem is some of them have cracked on the shoulder and neck after the first firing! Im using 39gr of H380 and a 50gr bullet, whats the deal? It shows in my book that 41gr is the max load so I dont think Im to hot but I could be wrong, and my primers are not completely flatend out, I can still see the round edges on them. Could this be a batch of bad brass?
