That hull looks about as normal as any. My Krieghoff is 52 years old, some of my Smiths are 125 years old or more and my AA empties are from 1 to 20 years old. I try to stay away from two piece hulls, but I have enough one piece AA hulls to last me a lifetime. I feel that the switch away from compression formed hulls was a ridiculous decision that causes all this confusion about blow up accidents. I have never had an accident in 60 years of shotshell reloading.
