I have been reloading for some time and safety is always paramount. I know to check for case head separation and to trim my brass and obviously the load itself. I have seen split case necks before and know what to do with them but I just encountered something new. Fired 5 times 308 brass not annealed since the factory. Ran in an LR-308 gas gun. Found a split on the shoulder on 20% of the cases. Was going to retire the lot after the next firing, but is it safe to shoot them again with this split? Not a particularly hot load, but still something new to me.
