If the body of the case is covered in powder residue (black carbon) then the case failed to seal off the chamber, which is the real purpose of the cartridge case along with holding the components together for handling. I see no carbon on the case body (the picture is a bit hard to really determine that... get a camera that allow close focusing next time) and if that is the case then the split really is academic as the case did its job.
The bottom line is the case is meant to be a throw away. If it does its job but splits in the process who cares? Now if every case does that, no matter the case material, there may be a chamber problem because the chamber may be way too big, making the case have to expand beyond normal limits.
i understand the throw away part about the steel cases, this was a new out of the box shell it doesnt have any burnt powder or anything on it nice and clean, i was just wondering what would cause it to split, i thought it was a tight fit inside the gun so i didnt think there was enough room to split
this is the first one ive seen do that so i guess its just a fluke maybe,, thanks
