I believe when they researched the incident the culprit was whenever changing shifts they had to unload their rifle and show clear before turning it in. The cartridge in the chamber was always placed back into the magazine as the top round and on the next shift was rechambered and so on. After this was done several times the primer compound got knocked out from the many light primer strikes and the round would fail to fire. I don't remember the exact link but will try to find it. So not only do you have to worry about the rifle firing when chambering but if done on a round that has been rechambered several times you now have to worry about it going off when you need it to. Moral of the story is always a dummy round when checking for function checks or anything else where you won't need to fire the rifle. And rotate your ammo if you chamber a round but don't fire it.
