[QUOTE="Barrelnut, post: 1472234, member: 74902"] How many times had the shell that split been reloaded? Belted magnums require a couple of advanced loading techniques to make the shells last longer for reloading. Basically you need to fire the shell about 3 times and neck size only until the case gets resistance when closing the chamber, then bump the shoulder back 2 thousands. This allows the shell to index off of the shoulder instead of the belt as belted shells were originally designed to do. Tons of stuff written about this on the forum. You need a set of these so you can measure the shell size from the datum of the shoulder to the base of the shell.
