steel case rim tore off, case got stuck in chamber.
Today i got caught flat footed at the range while i was shooting some steel cased tula 55 grain. The extractor tore off a piece of the rim and caused the case to stay in the chamber and i did not have anything to take it out with. The rifle is fairly new with only 250 rounds through it and prior to to this happening i was firing some q3131, only about 30 rounds, however. The gun has had a mix of tula, q3131, and federal bulk 223. From inspecting some cases i can see some scratches on some cases, a few have dents, and the steel cased ammo has visible carbon on the outside of the case. Some also show marks on the case head.
Details:
Psa 16" midlength upper, .078" gas port
H huffer
Stock spring
Bcm bcg
It did not take much to get the case out when i got home, i uses a wooden dowel that fit very snuggly in the bore and with a few taps with a 2.5 pound weight it came right out. The bcm bcg was purchased brand new from bcm and as far as i know it does not have the o ring installed, i have never taken apart the bolt. Was it just a bad case or could the extractor be providing to much tension?

OP:
FYI, A similar "stuck-case" happened to me back when I had a new AR and got some Tula ammo to go with it (I had shot Brass-cased before).
Nowadays I always carry a cleaning rod with me incase I get another stuck, but after Hundreds and hundreds more rounds (Tula/Wolf) it never happened again.

Before, I would have said it was a myth, but... it is exactly what happened to me. It Never happened again, though.
