At large, whereabouts unknown.
Strangely, I have one AR barrel that works perfectly with 223 commercial level ammo, but blows primers with 5.56 level ammo. I sent it out and had it rethroated to 5.56 spec, and the chamber itself was lengthened slightly in case it was short throated. It chambers and unfired ammo simply drops out of the chamber when inverted. Case length is always perfect since I trim cases at every loading.
I've come to blame it on demons, and removed it from use. It's an original DPMS barrel, so the original quality should have been good, it's older than Remingtons corporate raidership of DPMS. 'Tis but a mystery. I could shoot it, until it broke down, pull the mag and load it into another rifle and finish shooting it dry. I even swapped bolts around with different guns to see if I missed something in headspace. The problem stayed with the barrel. Probably a heat induced issue of some sort.
