[QUOTE="AZShooter, post: 957831, member: 5219"] Fred, I just talked with Mike at Nosler and he said the wall thickness is .016" The reason for my asking about the thickness has to do with my recent experiences with a 7mm/375 I made. The brass has a wall thickness of .0175". The third firing of the brass didn't want to extract. The bolt opened easily as before but rearward movement of the bolt hung up so badly that the bolt had to be tapped rearward! There is a shiny area just in front of the belt where the brass apparently didn't contract enough. It is my feeling that just like the WSSMs the thicker brass is an issue. I believe due to its thickness and the multiple firings that it has lost its ability to spring back away from the chamber. To be honest the symptom is similar to a bulged chamber. I encountered that once and it took multiple taps with a piece of wood hitting the bolt to remove the brass. The polished area was much larger on the brass too. This rifle has not been overloaded and doesn't show the symptom with virgin, once or twice fired brass. Showed up on third firing. I asked Mike about any issues with brass not springing back for easy extraction after multiple firings. He said they haven't encountered any. I will be very interested in your findings Fred.
