Is it normal for a case to split after only the 2nd firing? This would be a Starline brand 500 S&W case and it's only been loaded with light loads, i.e. 12.6 gr Trail Boss or 11.1 gr TiteGroup behind a 335 gr bullet, moderate taper crimp used throughout (not even a roll crimp!) ...should be around 1000-1100 fps and less than half the chamber pressure that this gun is designed for. I haven't inspected every case carefully yet, but I spotted one on the way out of the tumbler that had a 1/2" long jaggy split that ran straight down from the neck towards the base. Is this normal? Is it due to just normal manufacturing variation? Or what? Seems kinda soon for light loads in a gun designed for twice the chamber pressure that this brass has seen. Comments?
