This thread reminds me of the old story of the army drill instructor who was asked if the 7.62 Nato cartridge was the same thing as a .308. The instructor said, "I don't know nothing about no civilian guns." The SAAMI warning is about as significant as the warning on every box of ammo sold in America, i.e. This ammunition should only be fired in guns in good condition. Looks like someone could provide us with a link to all the stories of this ammo blowing up 223s across the land. Only problem is it's not happening and most likely never has.
